Objective To determine the expression of Caspase 8 and phospho-Akt(p-Akt)in condyloma acuminatum(CA)lesions, and to evaluate their significance. Methods Skin lesion samples were collected from 30 patients with CA, cancer tissue samples from 20 with cervical cancer, and normal skin samples from 20 healthy controls. All the samples were subjected to paraffin embedding. An immunohistochemical study was conducted to determine the expression and distribution of Caspase 8 and p-Akt in the above samples. Results The expression rate of Caspase 8 was significantly lower in CA lesions (23.33%)than in normal skin samples(90%, P < 0.01)and cervical cancer lesions(80%, P < 0.001). Moreover, the expression rate of p-Akt in CA lesions(93.33%)was significantly higher than that in the normal skin samples(90%, P<0.001), but lower than that in the cervical cancer lesions(95%, P<0.001). No significant correlations were observed between the expression of Caspase 8 and p-Akt in either CA lesions or normal skin samples. However, the expression of Caspase 8 was positively correlated with the expression of p-Akt in cervical cancer lesions(r=0.369, P<0.05). Conclusion Both suppressed apoptosis initiation of Caspase 8 and anti-apoptotic effect of p-Akt may be involved in the occurrence and development of CA.

OBJECTIVETo observe the effects of three traditional Chinese medicine (TCM) such as Amomi Fructus Rotundus, Perillae Folium and Angelicae Dahuricae Radix on lung-yang deficiency rats induced by compound factors.

METHODLung-yang deficiency rats were established with three-factor combination, such as smoking (exogenous evil effect on lung), swimming in common and ice water (cold body and exhaustoin) and drinking ice water (inhale cold). Meanwhile, rats were given water extracts of the three TCM by intragastric administration for 24 days everyday. Indexes such as general behavior, weight, rectal temperature, back temperature and grip strength were observed. Blood was collected to determine NO, IgG in blood serum. Lung and heart were dissected to measure organs index.

RESULTThe water extracts of Amomi Fructrs Rotundus, Perillae Folium and Angelicae Dahuricae Radix could markedly heighten weight, back temperature, grip strength, content of IgG in blood serum, reduce content of NO in blood serum, lung index and heart index. The water extracts of Amomi Fructrs Rotundus and Perillae Folium could heighten rectal temperature.

CONCLUSIONAmomi Fructrs Rotundus, Perillae Folium and Angelicae Dahuricae Radix were TCM with pungent-flavor, warm-nature and meridian tropism in lung, which could improve the symptoms of physique emaciation, aversion to cold of the back, weary and acratia and so on. It provides an important reference for the regularity of the properties theories about pungent-flavor, warm-nature and meridian tropism in lung.

Objective To screen the active components of Bushen Huoxue Decoction ( BSHXD) involved in promoting the proliferation of bone marrow mesenchymal stem cells ( MSCs). Methods BSHXD and its subdivisions were extracted with petroleum ether, ethyl acetate, water-free ethanol and water respectively. MSCs were isolated and cultured by the bone marrow adherent method. At the third passage, MSCs were identified by the specific surface markers with immunofluorescence, and their osteogenic and adipogenic differentiation were tested by alizarin red staining and oil red “O” staining. After treated with the extracts of BSHXD and its subdivisions at gradient concentrations for 24 hours, cell viability was detected by methyl thiazolyl tetrazolium (MTT) assay for the screening of active components and optimal concentration. MTT assay was used to describe the growth curve of MSCs treated with the most effective components, and cell cycle was analyzed by flow cytometry. Results Compared with the blank control group, the extracts of BSHXD and its subdivisions could protect MSCs from death to various degrees. Of all the extracts, the ethyl acetate extract of Bushen Division ( BSD) , ethyl acetate extract of BSHXD, ethyl acetate extract of Huoxue Division ( HXD) had the strongest effect, and the effect was dose-dependent, 100 μg/mL being the optimal active concentration while having no any cytotoxic reaction. The results of MTT assay revealed that BSD extracts promoted the proliferation of MSCs significantly and was the most effective component, and then came BSHXD. The results of flow cytometry indicated that BSD extract had the most strongest effect on increasing the amount of MSCs at proliferative phase, and then came BSHXD. Conclusion BSD ethyl acetate extract is the active component of BSHXD for promoting the proliferation of MSCs, showing an effect on increasing the proportion of MSCs at proliferative phase.

BACKGROUND:Mechanical stress plays an important role in the progressive collapse in osteonecrosis of the femoral head.Therefore,the bone structure of weight-bearing area may be the risk factor for collapse.OBJECTIVE:To investigate the relationship between the bone preservation of weight-bearing area and collapse progression in necrotic femoral head.METHODS:Eighty-seven patients (102 hips) with ARCO stage Ⅱ osteonecrosis of the femoral head,diagnosed by MRI,were enrolled.All patients underwent a natural progression.Collapse and bone involvement of the weight-bearing area were viewed by anteroposterior and frog-leg lateral radiographs.According to the location of the necrotic lesion on the anterolateral portion of the femoral head,the necrosis was divided into three types:type 1,the posteromedial and central portions;type 2,part of the anterolateral portion;type 3,the entire anterolateral portion.The collapse rate and the time to collapse in different types were assessed.RESULTS AND CONCLUSION:(1) All patients were followed up for 3-58 months.(2) Of the 60 hips with collapse,46 (76.7％) hip collapse was identified on anteroposterior radiograph.On frog-leg lateral radiograph showing collapsed femoral head could be identified in 57 (95.0％) hips,which was significantly different (P ＜ 0.01).(3) In all 102 hips,the collapse rate in type 3 osteonecrosis of the femoral head was significantly higher than that of type 2 osteonecrosis of the femoral head (P ＜ 0.001),and the time to collapse was markedly shortened.None collapse occurred in all six hips with type Ⅰ osteonecrosis of the femoral head during follow-up.(4) In summary,preservation of anterolateral portion is associated with potential collapse progression in necrotic femoral head.

Objective To investigate th grade of CT in colonic diverticulitis and the value in predicting clinical treatment.Methods CT data of totally 41 patients with colonic diverticulitis were analyzed retrospectively.According to the imaging signs,the grading of diverticulitis cases was performed.Patients with level 1 to 3 were considered as only need non-operative treatment,those with level 4 or 5 were considered as need surgical treatment.The consistency of predictive treatment plans were contrasted with clinical practical treatment results.Results The CT features of colonic diverticulitis were saclike protrusions bulged outside of the bowel wall with colon wall thickening in 40 cases (40/41,97.56％) and fuzzy pericolonal fat space in 39 cases (39/41,97.12％).The diagnostic accuracy of preoperative CT grading in predictive treatment plan was 85.37 ％ (36/41).Conclusion Colonic diverticulitis have certain characteristic CT findings.CT grading of diverticulitis is helpful to formulate appropriate clinical treatment.

BACKGROUND:The majority of studies on developmental dysplasia of the hip focus on hip malformations,but there are few reports on the effects of acetabular dysplasia on the spine. OBJECTIVE:To investigate the compensation of spinopelvic parameters in coronal and sagittal views in patients with developmental dysplasia of the hip,and to explore the correlation between acetabular development and spinopelvic parameters. METHODS:A total of 101 patients with developmental dysplasia of the hip admitted to the Third Affiliated Hospital of Guangzhou University of Chinese Medicine from January 2018 to June 2022 were selected as the trial group,and 114 healthy subjects were selected as the control group during the same period.The spinopelvic parameters of the subjects were measured through the full-length X-ray films of the coronal and sagittal spines:lumbar lordosis,anterior pelvic tilt,thoracolumbar kyphosis,Cobb angle,and the distance between the C7 plumb line and the center sacral vertical line,sacral slope,pelvic incidence,and thoracic kyphosis.The differences in spinopelvic parameters were compared between the two groups.In addition,the differences in spinopelvic parameters in patients with unilateral,bilateral and different Crowe classifications of developmental dysplasia of the hip were compared.Pearson correlation analysis was used to explore the correlation between Sharp angle and spinopelvic parameters. RESULTS AND CONCLUSION:(1)In the sagittal view,the lumbar lordosis in the trial group was significantly lower than that in the control group(P<0.05).The pelvic tilt and kyphosis angle of the thoracolumbar segment in the trial group were significantly greater than those in the control group(P<0.05).In the coronary position,the Cobb angle and the distance between the C7 plumb line and center sacral vertical line in the trial group were significantly greater than those in the control group(P<0.05).There was no significant difference in the remaining spinopelvic parameters between the two groups(P>0.05).(2)The lumbar lordosis of patients with bilateral developmental dysplasia of the hip was significantly lower than that of patients with unilateral developmental dysplasia of the hip(P<0.05).The pelvic tilt,thoracolumbar kyphosis,Cobb angle and the distance between the C7 plumb line and center sacral vertical line in bilateral developmental dysplasia of the hip patients were significantly greater than those in unilateral developmental dysplasia of the hip patients(P<0.05).(3)The lumbar lordosis decreased with the increase of Crowe classification severity(P<0.05).The pelvic tilt increased with the severity of the Crowe classification(P<0.05).(4)Pearson correlation analysis showed that Sharp angle was negatively correlated with lumbar lordosis(P<0.05),while Sharp angle was positively correlated with anterior pelvic tilt,Cobb angle,C7 plumb line and center sacral vertical line(P<0.05).(5)It is concluded that the pelvic tilt,thoracolumbar kyphosis,Cobb angle and the distance between the C7 plumb line and center sacral vertical line increase,while lumbar lordosis decreases in developmental dysplasia of the hip patients.The degree of acetabular dysplasia was significantly correlated with lumbar lordosis,pelvic tilt,Cobb angle,C7 plumb line and center sacral vertical line.
