Objective To study the effect of using improved loop electrosurgical excision procedure for diagnosis and treatment of cervical diseases. Methods The clinical data of 70 cases of cervical intraepithelial neoplasia or carcinoma in situ from January 2006 to Decemder 2008 in our hospital was collected.The operation time, the mean volume of blooding, days of blooding, relationship between the mean blood and areas of pyramid area of pyramid was compared between study group and control group. Improved loop electrosurgical excision procedure was executed on 21 cases of study group ( CIN Ⅰ 4 cases, CIN Ⅱ 10 cases,CIN Ⅲ4 cases, CIS3 cases ) and loop electrosurgical excision procedure was used on 49 cases in control group (CIN Ⅰ7 cases,CIN Ⅱ21 cases, CIN Ⅲ 16 cases, CIS5 cases). Results Blood loss [(16.57 ±17. 47 ) ml], operative time [( 9.07 ± 3.34 ) min] and postoperative bleeding time [(9.10 ± 2.23) d] in study group were lower than that in control group [( 39.80 ± 37.43 ) ml, ( 12. 19 ± 5.34 ) min, ( 10. 49 ±2. 76)d], and the differences were statistically significant ( P < 0. 05 ). Cervical cone volume [( 14. 70 ±13. 35 ) mm3] and blood loss [(32. 83 ± 14. 32 ) ml] were positively correlated ( r = 0. 430, P < 0. 05 ). No significant difference between prognosis of two groups was found( P >0. 05 ). Conclusion There was positive relationship between the averge blood loss in surgery and areas of pyramid excision. It'd be better to stitch the ramus descendents of uterine artery at three and nine o'clock of the cervix uteri, when the patients were expected to have large pyramid areas and abundant blood flow who may bleed more than normal. which can reduce the blood loss after surgery and reduce the time of surgery.

Objective To analyze the change trend of hospitalized patients with pulmonary embolism in Wuzhou city during 2004-2014,and analysis of its risk factors.Methods From January 2004 to January 2014,from four comprehensive tertiary hospitals of Wuzhou city,we selected hospitalized cases of pulmonary embolism as investigation subjects,which from 2004 to 2008 were selected as control group,and from January 2009 to January 2014 were selected as observation group.The hospitalization rate,mortality rate and risk factors were compared between the two groups.Results From 2004 to 2008,there were 257 370 cases of hospitalized,pulmonary embolism hospitalized in 52 cases at the same period,accounting for 0.02％ of the total hospitalized cases.From January 2009 to January 2014,there were 367 728 cases of hospitalized,pulmonary embolism hospitalized in 115 cases at the same period,accounting for 0.03％ of the total hospitalized cases.The proportion of pulmonary embolism in total hospitalization between the two groups had statistically significant difference (P ＜ 0.05).From 2004 to 2008,in 52 cases of pulmonary embolism,24 cases (46.15％) died,includef 16 cases(30.7％) died of pulmonary embolism,and the rest 8 cases(15.38％) died of the complication.From 2009 to 2014,in 115 cases of pulmonary embolism,30 cases (26.08％) died,included 23 cases(20.00％) died of pulmonary embolism,and the rest 7 cases(6.08％) died of complications.The difference of the mortality rate in the two periods was statistically significant (x2 =3.879,P ＜ 0.05).52 cases of pulmonary embolism of the control group were selected to study risk factors and basic diseases,the risk factors and basic diseases of pulmonary embolism had 11 kinds,the highest frequency was in lower limb venous thrombosis,followed by surgery and lie in bed for a long time,again for malignant tumor,smoking,fracture,hyperlipidemia,arrhythmia(atrial fibrillation,etc.) and diabetes,etc.Conclusion The hospitalization proportion and mortality trend of hospitalized patients with pulmonary embolism in Wuzhou city remains unchanged,to study the risk factors in order to get a better prevention and treatment measures.

Objective To analyze the accuracy,sensitivity and safety of multidetector CT angiography(MDCTA) and DSA;furthermore to explore the clinical value of MDCTA in studying the delayed cerebral vasospasm(DCVS) .Methods Delayed cerebral vasospasm was induced in 17 rabbits by injection of autologuous blood into the cisterna magna and followed by a second injection 24 hours later.MDCTA and DSA were carried out at the 7th day before and after the procedure in order to obtain the data of vascular diameter changes for comparative study.Results The basilar artery diameters detected by MDCTA were shown preoperatively as(1.55 ? 0.14) mm and postoperatively as(0.95 ? 0.20) mm;and detected by DSA as(1.61 ? 0.19) mm and(1.00 ? 0.17) mm postoperatively;showing statistically equivalence between the two methods.Conclusions MDCTA is recommended as a reliable,rapid,and minimally invasive diagnostic method,providing a new technique for the delayed cerebral vasospasm research.

Objective To review the three-dimensional characteristics and configuration of cranial base arteries of patients with intracranial berry aneurysms. Methods All the 70 patients with intracranial berry aneurysms (83 cases)were admitted from January to December in 2007. Their images of spiral computer angiography (CT) were presented and analyzed retrospectively. The site, size and figures of aneurysms were recorded, especially the variations of cranial base arteries were analyzed. Results Cerebral anterior communicating artery (ACoA) was the frequent site where aneurysms located. Incidence of ACoA aneurysms was 43.37%(36/83), that of posterior communicating artery (PCoA) was 28.92%(24/83), that of internal carotid artery was 9.64% (8/83), that of middle cerebral artery was 6.02% (5/83), that of A1-A3 was 3.61% (3/83), that of basilar artery was 3.61% (3/83), that of posterior cerebral artery was 2.41% (2/83), that of posterior inferior cerebellar artery was 1.20% (1/83),that of anterior choroidal artery was 1.20% (1/83).The shape of many berry aneurysms was regular. Mutational rate of cranial base arteries among aneurysms were 56.63% (47/83) and ACoA ancurysms with A1 dysplasia rate was 72.22% (26/36). Conclusions The solid shape and vascular variation of intracranial berry aneuryams can be optimally identified by spiral computer angiography. The occurrence of berry aneurysms might be associated with variation of cranial base arteries.

Objective To access the expression of germ P16 in cervical cancer patients , find out the connection between with the expression in germ of P16 and the prognosis of cervical cancer , and discuss whether P16 can role as an indicator to predict the prognosis. Methods The pathological sections of all 74 cases were tested for the presence of P16 germ , using an immunohistochemistry technique. And the results were analyzed to investigate the value of P16 on the prediction of prognosis of cervical cancer. Results Of all 74 cervical cancer cases, there are 63 cases show positive expression of P16, with the positive expression rate of 85% (63/74). The positive expression of gene P16 is associated with the prognosis of cervical cancer (P = 0.041). The cumulative survival rate for two years of the positive expression set is 85.2%, and the negative set 100%, which is statistically significant (P = 0.043). Positiveexpression of P16 is closely related (P < 0.05) with clinical stages LVSI and interstitial infiltrates, but is irrelevant (P > 0.05) with TNM and histological differentiation. Conclusions We suggest that the expression of germ P16 is closely connected prognosis in cervical cancer , and it might be used as one of indicator to predict the prognosis of cervical cancer.

Objective To investigate the value of multi-slice computed tomography angiography (MSCTA)in the detection of intracranial micro-aneurysms(aneurysm≤3 mm in maximal diameter, IMA).Methods The clinical history and images of 826 patients with suspected intracranial aneurysms were retrospectively analyzed.All patients underwent MSCTA on 16-slice row CT before hospitalization(from 2 h to 4 d after symtom onset).All intracranial aneurysms were confirmed by digital subtraction angiography (DSA), three-dimensional rotational angiography (3DRA) or surgery.Two independent radiologists assessed all the images.The MSCTA findings were compared with the DSA/3DRA results.The sensitivity, specificity, and accuracy of MSCTA for diagnosis of IMA was calculated.The diagnostic consistency between DSA/3 DRA and MSCTA was determined by Kappa statistics.The prevalence of multiple aneurysms between the group of patients with IMA and the group of patients without IMA was evaluated by Chi-square test Results A total of 889 aneurysms in 788 of the 826 patients were detected.Among them, 706 patients had single aneurysm and 82 patients had multiple aneurysms.No aneurysms were detected in 38 patients.Among the 212 patients who underwent DSA/3 DRA, 271 aneurysms were found and 232 were IMA.MSCTAdetected 229 IMA.There was 1 false-positive finding and 4 false-negative findings by MSCTA.The sensitivity, specificity and accuracy of MSCTA for IMA was 98.3% (228/232), 97.4% (38/39), 98.2% (266/271).There was excellent agreement between two techniques (Kappa=0.927, P<0.05).The prevalence of multiple aneurysms was 21.2% (45/212) in the patient group with IMA and 6.4% (37/576) in the group without IMA.There was statistically significant difference between the two groups (X~2=36.421, P<0.01).Conclusions The detection value of IMA by MSCTA was high.The cutoff level of diameter of intracranial IMA should be adjusted from 4-5 mm to ≤3 mm.

Objective To investigate the value of computer aided design and 3D printing model in operation for complex mandibular fractures.Methods The clinical data of 136 patients with complex mandibular fractures treated from June 2006 to June 2016 were retrospectively analyzed.The patients were divided into 3D group (n =28) and conventional group (n =108) based on the use of computer aided design and 3D printing model.There were 24 males and four females in 3D group,with the age of (33.8 ± 15.4) years.There were 91 males and 17 females in conventional group,with the age of (30.3± 11.9)years.The 3D group used computer aided design and 3D printing model to develop the surgical plan,and the conventional group used traditional CT scan image data.The operation time,intraoperative blood loss,incidence of postoperative adverse events,and the distance differences between the ipsilateral and the five contralateral maxillofacial markers were compared between the two groups (△L1:the difference between the mandibular angle point and the condyle apex;△L2:the difference between the mandibular angle point and the chin vertex;△L3:the difference between the apex of the chin and the apical point;△L4:the difference between the inner mandibular angle point and the Inferior alveolar margin point;△L5:the distance between the inner mandibular angle and the sagittal plane).Results The operation time in the 3D group and the conventional group were 155 (126.25,183.75)min and 235 (156.25,268.75)min,respectively.The intraoperative blood loss in the 3D group and the conventional group were 100 (50.0,187.5) ml and 125 (100.0,200.0) ml,respectively.In the 3D group,one patient had mild occlusion disorder.In the conventional group,4 patients had postoperative infection,1 repulsion reaction of internal fixation device,and 19 mild occlusion disorder.The differences between the two groups in operation time and postoperative adverse events were statistically significant (P ＜ 0.05),but there was no significant difference in intraoperative blood loss (P ＞ 0.05).There was no significant difference between the ipsilateral △L and contralateral △L in two groups (P ＞ 0.05).No significant difference in △L4 was found (P ＞ 0.05),but there were significant differences in △L1,△L2,△L3,and △L5 between the two groups (P ＜0.05).Conclusion For patients with complex mandibular fractures,the use of computer-aided design and 3D printing model can helps shorten operation time,reduce postoperative adverse events and hence improve the fracture reduction outcome.

Objective:To study the morphologic features of the fusion site of proximal tibial epiphysis in normal adults and analyze its potential clinical value based on Mimics three-dimensional (3D) reconstruction.Methods:CT images of knee joint of 68 patients without obvious abnormalities of lower limbs were retrospectively analyzed in electronic database of our hospital from June 2020 to June 2021, including 41 males and 27 females. The mean age of the patients was 38.7±8.4 years (range, 25-55 years), and the mean body mass index (BMI) was 25.3±4.0 kg/m 2 (range, 18.75-41.8 kg/m 2). Mimics 3D reconstruction technique was used to reconstruct the 3D model of the proximal tibia and epiphyseal fusion site. The relationship between the surface area of epiphyseal fusion site and age and BMI was studied, and the changes of cortical thickness and density at epiphyseal fusion site were also explored. Results:The fusion site of adult epiphyseal reconstructed by Mimics 3D reconstruction is a complex wavy surface structure in 3D space. The surface area of the epiphyseal fusion site was 2,994.7±645.3 mm 2 (range, 1,704.0-4,650.0 mm 2) obtained by 3-Matic Research 12.0. The fusing area of male epiphysis was 3 269.3±533.9 mm 2 than that of female 2,577.6±578.7 mm 2, the difference was statistically significant ( t=5.06, P<0.001). However, there was no significant correlation between the epiphyseal fusion site surface area and age ( R2=0.02, P=0.268) and BMI ( R2=0.04, P=0.125). Mimics software was used to obtain the CT values of bone cortex at the epiphysis line and the distal end of the epiphysis line at 10 mm and 20 mm levels as 451.059±74.953 Hu, 1,018.412±125.732 Hu and 1,414.162±107.848 Hu, respectively. The thickness of bone cortex was 1.814±0.090 mm, 2.511±0.089 mm and 3.189±0.185 mm at 10 mm and 20 mm layers of epiphysis line and distal epiphysis line, respectively. Conclusion:In this study, Mimics 3D reconstruction technique was used to visualize the fusion site of the proximal tibial epiphysis in normal adults. The epiphyseal fusion site of adult is a undulating plate-like structure, and the cortical bone density of epiphyseal fusion site is low and thin, theoretically, it is easy to fracture under indirect violence.
