Objective:To investigate the types of non-tumor diseases in patients with cancer, and to explore the effects of those dis-eases on the diagnosis and treatment of cancer patients. Methods:We collected the medical records of cancer patients from January 2013 to December 2017 in Peking University Cancer Hospital, and screened for non-tumor diseases. The clinical records of the patients in this group were analyzed retrospectively, and the effects of those diseases on the diagnosis and treatment of tumors were dis-cussed. Results:Of the 1,323 cases of inter-hospital consultation, 1,153 cases of non-tumor disease (87.2％) were selected. There were 773 men (67.0％) and 380 women (33.0％) included. The median age was 62 (14-90) years. The primary tumor types included lung can-cer, gastric cancer, lymphoma, colorectal cancer, esophageal cancer, breast cancer, malignant melanoma, liver cancer, cholangiocarci-noma/gallbladder cancer, pancreatic cancer, and other tumors. Non-neoplastic diseases included cardiovascular disease in 356 cases (30.9％), respiratory system disease (17.0％) in 196 cases, digestive system disease in 107 cases (9.3％), skin and venereal diseases in 81 cases (7.0％), nervous system lesions (6.4％) in 74 cases, urinary system disease in 72 cases (6.2％), blood disease in 70 cases (6.1％), en-docrine and metabolic diseases in 47 cases (4.1％), autoimmune disease in 23 cases (2.0％), and other diseases (11.0％) in 127 cases. Impact on tumor diagnosis and treatment was as follows:direct, 771 cases (66.9％);no influence, 313 cases (27.1％);and uncertain, 69 cases (6.0％). Conclusions:Cardiovascular disease is a major non-tumor disease associated with cancer. Non-neoplastic diseases are important factors affecting the diagnosis and treatment plans of cancer.

Objective To observe effects of different extracts of Jianpi Huogu Formula (JPHGF) on proliferation and differentiation of bone marrow mesenchymal stem cell (BMSCs). Methods Whole bone marrow adherent was used to screen, culture, and isolate BMSCs. Extracts from different parts (water, chloroform, ethyl acetate and n-butanol parts) of JPHGF were administrated for a certain time. MTS was used to detent cell proliferation;ALP staining was used to detect ALP activity;ARS staining was used to detect the formation of calcium nodules;oil red O staining was used to detect fat cell formation. Results Extracts from different parts of JPHGF could promote cell proliferation of BMSCs in different levels, followed by its strength in water, chloroform, ethyl acetate, and n-butanol parts;ALP staining results showed that the intensity of ALP expression of the order is water, acetic acid ethyl, chloroform and n-butanol parts;in promoting the formation of calcium nodules, ARS staining results showed that its intensity were water, chloroform, ethyl acetate, and n-butanol parts;oil red O staining results showed that inhibition intensity of fat cells interaction strength was formed from ethyl acetate, water, chloroform to n-butanol parts. Conclusion Extracts from different parts of JPHGF have different effects on BMSCs proliferation and differentiation. Water extraction has the strongest osteogenic differentiation and proliferation, and ethyl acetate has the best effect on the inhibition of cell formation.

OBJECTIVETo observe the effect of Huogu II formula compatible with different channel ushering drugs on the homing of bone marrow stem cells of osteonecrosis of the femoral head (ONFH) induced by liquid nitrogen freezing in rabbits and discuss the mechanism for preventing and treating ONFH.

METHODThe ONFH model was established by liquid nitrogen freezing of 84 rabbits. They were randomly assigned to the model group and the Huogu II formula group and groups of Huogu II formula combining with Achyranthis Bidentatae Radix, Asari Radix et Rhizoma, Angelicae Pubescentis Radix, Platycodonis Radix. The remaining 14 rabbits were sham-operated. During the course of ONFH modeling, all of the rabbits were subcutaneously injected with recombinant human granulocyte colony-stimulating factor (rhG-CSF)(30 microg x kg(-1) x d(-1), for consecutively 7 days). Meanwhile, normal saline and decoction of the formulae were orally administrated respectively. WBC was counted in peripheral blood before and after the injection of rhG-CSF. HE stainings at the 2nd and the 4th weeks after the modeling were adopted to observe histopathological changes, vascular morphology was observed by ink perfusion, BrdU and SDF-1 were determined by immunohistochemical assay in femoral heads of the left hind leg.

RESULTCompared with the sham-operated group, the Huogu II formula group showed decrease in the ratio of empty lacuna and increase in vessel area, number of BrdU positive cells and SDF-1 level. In comparison with the model group, the Achyranthis Bidentatae Radix group displayed decreasing empty lacuna ratio and increasing vessel area at the 4th week and increasing SDF-1 at the 2nd week; the Platycodonis Radix group revealed a notably increasing empty lacuna ratio and a sharp decrease in the number of BrdU positive cells at 4th week; Asari Radix et Rhizoma and Angelicae Dubescentis Radix groups showed no remarkable change.

CONCLUSIONHuogu II formula can promote the directional homing of bone marrow stem cell to the necrosis area. Channel ushering drug achyranthes can further boost above effects of Huogu II formula.

OBJECTIVETo investigate the effect of two treating principles and formulas, which are named 'invigorating spleen to remove phlem and promoting blood circulation to remove meridian obstruction' (Jianpi) and 'invigorate the kidney and promoting blood circulation to remove meridian obstruction' (Bushen), on the expression of osteogenic factors in steroid-induced osteonecrosis of the femoral head (SONFH), such as bone morphogenetic protein 2 (BMP2) and transforming growth factor beta1 (TGFbeta1) and Smads, as well as to explore and compare their mechanisms of prevention and treatment of SONFH.

METHODAnimal model of SONFH was established by injection with methylprednisolone in chest muscle on chickens. 48 SONFH chickens were randomly assigned to model, Jianpi and Bushen group. Another 16 normal chickens served as control group. At the 8th and 16th week, the expression of BMP2, TGFbeta1, Smad4 and Smad7 of bilateral femoral heads were detected with immunohistochemistry.

RESULTThe expression of BMP2, TGFbeta1 and Smad4 decreased, and Smad7 increased significantly in model group compared with control group. The expression of BMP2, TGFbeta1, Smad4 increased and Smad7 decreased significantly in Jianpi group at the 8th week compared with model group, and the same changes in Bushen group at the 16th week.

CONCLUSIONBoth Jianpi and Bushen formulas exerted preventive and therapeutic activity on SONFH through regulating the expression of BMP2, TGFbeta1, Smad4 and Smad7 to promote bone repair. Notably Jianpi formula took effect earlier than Bushen formula

BACKGROUND:The majority of people do not believe that the femoral component flexion in total knee arthroplasty affect or affect little postoperative function and it is the only that the radiographic films is not satisfactory.So it has not caused people's enollgh attention.But the femoral component flexion affects the results of total knee arthroplasty obviously.OnJECTIVE:To investigate the curative effects of femoral component installed in the position of flexion during the operative procedure of total knee arthroplasty(123 knees)on the follow up results in 78 patients.DESIGN:Grouping contrast observation.SETTlNG:First Department of Bone and Joint,Wangjing Hospital of China Academy of Traditional Cllinese Medicine.PARTlCIPANTS:123 knees(78 patients)were given total knee arthroplasty in the First Department of Bone and Joint,Wangjing Hospital of China Academy of Traditional Chinese Medicine from October 2001 to June 2004.Seventeen(13.8%,15 patients)knees were found with femoral component flexion(FCF),in which there were 5 male cases and 10 female cases,aged from 47 to 81 years old.106(63 patients)knees were found without FCF,in which there were 22 male cases and 41 female cases,aged from 47 to 79 years old.METHODS:Total knee arthroplasties about their HSS rating scores,ranges of motion and flexion contractures werecompared in the two groups before operation and after operation,and the degrees of the FCF angle and the distances of femoral component flexion were measured.MAIN OUTCOME MEASURES:①Femoral Drostllesis flexion measurement;②HSS scores and activity:③femoral prosthesis flexion angle and distance buckling;④adverse events and side effects.RESULTS:Follow up lasted for one year above.①The degrees of flexion of femoral components were from 7°to 19°(average 11.3°)and the distance of flexion was from 2 mm to 4 mm(average 2.6 mln)in those 17 knees of total knee arthroplasty.②Differences in HSS rating scores and range of motion were not statistically significant(P＞0.05)before operations between the group of femoral component flexion and the group of femoral component plane.However,after operations the above aspects in the group of femoral component flexion were less than that in the group of femoral component plane significantly(P=0.01,P＜0.01),and were statistically significant(P=0.02,P＜0.01)between post-operations and pre-operations in HSS rating scores and range of motion respectively in the two groups.③The statistic differences in cases and angles of flexion contractures of postperations between the group of femoral component flexion and the group of femoral component plane were significant(P＜0.01),the situation in the group of femornl component flexion were more bad than that in the group of femoral component plane,but were all improved significantly in cases and angles of flexion contractures after operations in the two groups(P＜0.05,P＜0.01).④There was one case with the right deep venous thrombosis and one case with myositis ossifican in non-FCF group,and there was one case in FCF group with impingement sign between patellar and component.CONCLUSION:The findings show that femoral component flexion will increase the incidence of knee flexion contracture and result in knee extension dysfunction after total knee arthroplasty surgery.

[Objective]To study the correlation between the severity of bone marrow edema(BME) and the collapse of osteonecrosis of the femoral head(ONFH),to explore the relationship between the severity and the score of Harris,so as to offer the direction for understanding and judging the prognosis of ONFH clinically.[Method]Fifty-eight cases of ONFH patients(94 hips) without collapse,according to the X-Ray and the MRI examination,made a follow-up visit for 16～28 months,an average of 18 months,and made a retrospective study of the correlation between the severity of BME and the collapse,the Harris of ONFH.[Result]The correlation between the BME degree and the collapse of ONFH:the collapse rate was 4.5% in degreeⅠ,11.8% in degreeⅡ 66.7% indegreeⅢ,90% in degree Ⅳ.The correlation between the BME degree and the Harris:93.0?5.41 in degree Ⅰ,84.1?5.42 in degree Ⅱ,76.4?4.22 in degreeⅢ,66.3+7.46 in degree Ⅳ.[Conclusion](1)BME is the secondary sign of ONFH;(2)The tendency of collapse could be predicted through the BME;(3)There is a negative correlation between the BME degree and the Harris,namely the larger scope of BME is,the lower the score of Harris is.

[Objective] Domestic literatures on misdiagnosis of osteonecrosis of femoral head(OFH)in the past 15 years are reviewed to distinguish OFH from other 9 similar diseases.The symptoms in early,middle and late stages of OFH are similar to other diseases,which is easy to be misdiagnosed as OFH.Pathological changes in different hip joint diseases have different specific performances.Careful and discriminative diagnosis is important in clinical practice.

The pathomechanism of hip pain and hip osteoarthritis is multi-factorial.Recently,abnormal impingement between proximal femur and the acetabular rim,femoroacetabular impingement(FAI),has been recognized as a relatively common and possibly prearthritic cause of these symptoms.Accurate diagnosis of the impingement disease pattern is the basis of successful surgical care.The article summarizes the pathomechanism of three types of femoroacetabular impingement and important diagnosis criteria.In addition,this paper further explores requirements for a diagnostic pelvis radiograph and multiple-parameters in pelvic imaging concerning femoroacetabular impingement,such as acetabular retroversion alpha angle,offset,the offset ratio.It will improve the diagnostic rate of FAI and formulating a reasonable treatment plan,so that the therapeutic effect of hip joint disease is improved.
