bone fracture, mild col apse of the articular surface;femoral head deformation, bone fracture, articular surface col apse, hip degeneration. MRI of four categories of avascular necroses appeared as phase Ⅰ:line-like low signal of weight-bearing area of femoral head on T1WI, high signal on T2WI as the main change. Phase Ⅱ:clear boundary crescent-shaped uneven signal on T1WI, T2WI displayed moderately higher, uneven slightly lower signal around, showing a typical two-line sign. Phase Ⅲ:femoral head deformation, subchondral fracture, col apse, crescent formation, zonal low signal on T1WI, medium or high signal on T2WI. Phase Ⅳ, Ⅴ:complete destruction of articular cartilage, joint space narrowing, significant col apse and deformation of the femoral head, non-specific secondary osteoarthritis of the acetabulum, such as sclerosis, cystic degeneration and marginal osteophyte. The X-ray, CT, MRI performances of four types of avascular necroses at the same period were basical y the same.

Objective: To observe the clinical efficacy of Kang' ai injection combined with transcatheter arterial chemoembolization (TACE) on hepatocellular carcinoma (HCC). Methods: All of 67 patients with HCC were divided into two groups: the observation group (n = 36) and the control group (n = 31). Control group received TACE therapy only, and the observation group was given Kang' ai injection combined with TACE. The response rate (RR), KPS scores, body weight, and adverse reaction were observed. Results: The short-term efficacies of observation group and control group were 44.4% and 41.9%, respectively. The difference was not significant (P >0.05). The KPS score of the observation group was elevated after treatment, and the difference was significant (P < 0.05). But the KPS score of the control group tended to decrease after treatment, but there was no significant difference (P >0.05). The body weight was not significantly different before and after treatment in the 2 groups (P >0.05). The occurrence rate of adverse drug reaction such as leucopenia, hemoglobin decrease, and liver function damage were lower in the observation group than that in the control group (P <0.05). The incidencs of thrombocytopenia, nausea or vomiting, and renal function damage had no significant difference between the two groups (P >0.05). Conclusion: Kang' ai injection combined with TACE improves the life quality of patients and decreases adverse reactions induced by chemotherapy.

A simple and effective method for the duplex PCR detection was developed by using sequences of exogenous gene(RDV MP-)and endogenous gene(Zein)as templates for PCR amplification.The results of routine PCR amplification for RDV MP-gene in transgenic maize suggested that RDV MP-gene can stably inheritate in transgenic plants and their progenies;The duplex PCR detection of all negative and part positive samples that obtained by routine PCR amplification confirmed that above negative results were exact,also showed that the quality of extracted DNA can meet the need of PCR amplification.The error ratio of negative samples was 1.4%.The method used in this study was simple and credible and can be used to detect transgenic plants and their products.

Objective To study the application of spiral CT three-dimensional reconstruction in diagnosing intra-articular and other bone fractures in the earthquake of Wenchuan.Methods 25 cases with joint and other bone fractures in Wenchuan earthquake underwent multi-slice spiral CT volume scanning,the images were dealed with three-dimensional reconstruction at workstation including multiplanar reconstruction (MPR) and surface shaded display(SSD) to observe the fractures.Results 36 fractures in 25 cases were found by three-dimensional reconstruction(MPR and SSD),which included knee joint bone fracture in 6,one case was avulsion fracture of the point attached to the tibia by posterior cruciate ligament and missed by X-ray;ankle fracture in 3,1 case was Pilon fracture;shoulder fracture in 5,one case with glenoid anterior labrum missed by radiography;elbow fracture in 3;spinal fractures including cervical vertebra in 2,thoracic vertebra in 4 and lumbar vertebra in 5,2 cases were burst fracture accompanied with the articular process fracture; pelvis bone fracture in 8,1 case was sacroiliac fracture accompanied with sacroiliac separation.There were open bone fractures in 4 cases,fractures with dislocation in 6 cases,soft tissue swelling in different degree around the fractures in 25 cases.Conclusion Spiral CT three-dimensional reconstruction of bone can directly and really show the fractures that will provide in-formations for the clinical diagnosis and treatment .

Objective To analyze the potential risk factors of infantile spasms (IS) relapse through following up the respondents with IS after different treatment protocols.Methods Sixty-nine cases were collected in the Department of Pediatric Neurology,Jiangxi Children's Hospital from May 2011 to September 2013,who had complete cessation of spasms for at least 28 days or more after the different treatment protocols.The follow-up was performed on these patients until spasms seizure relapse or at least 1 year for those without recurrence.According to the literature review,8 possible risk factors of IS recurrence (gender,age of onset,course of diseases,etiology,high irregular types of electroencephalogram,development quotient,onset time,treatment protocols) were selected,and then Logistic multiple regression was used to analyze the relationship of various potential risk factors with the relapse of spasms.Results (1) The recurrence rate at 6 months and 12 months were 40.6％ (28/69 cases)and 43.5 ％ (30/69 cases),respectively.(2) Among the various potential factors,the age at onset and the time to response were closely related to the IS recurrence.Namely,the non-classic onset(early-onset and late-onset) of IS were more likely to relapse than the classic onset[66.7％ (14/21 cases) vs 33.3％ (16/48 cases),x2 =6.605,P =0.010];the responders beyond 1 week were more likely to relapse than those within 1 week[63.6％ (14/22 cases) vs 34.0％ (16/47 cases),x2 =5.341,P =0.021].There were significant differences between the 2 groups (all P ＜ 0.05).(3) Logistic multiple regression analysis demonstrated that age at onset (Wald =3.603) was most closely related to the relapse of spasms.Conclusions (1) The relapse rate of IS in children was high,and the majority of them relapsed within 6 months.So a long-term,rational and effective clinical management solution should be explored.(2) The age at onset and the time to response are very important risk factors of the IS recurrence,and the former was more significant.So,early diagnosis and early treatment are more likely to improve the efficacy of IS,and reduce the risks of recurrence and improve the prognosis.

Objective To explore the clinical features,diagnosi s and prognosis of incontinentia pigmenti.Methods Analyzing and summarizing the clinical characteristic, diagnosis and prognosis of neonatal incontinentia pigmenti in 6 neonatal infants that were hospita- lized in our department during the period from January 1 998 to December 2003 were studied,and some relevant literature were reviewed. Results 1.Three of 6 infants were male which was unusual;2.Four infants had typical skin lesions at birth and 1 case at 6 days old.Four cases had typical 3 stages o f skin lesions including the erythematous and vesicular inflammatory stage,verr ucous lesions and hyperkeratosis stage,macular hyperpigmentation stage,but the re was overlap;3.Four infants were complicated by central nervous system involv ement (two cases presented mental retardation,2 infants were temporary damage). Two cases were complicated by ocular manifestations ( one case had optical nerve atrophy and blind in left eye,the other had severe bilateral retinal lesions); 4.On specific examination 5 infants were diagnosed by skin biopsy.Gene analysis was made in 1 case,but we didn′t find the mutations of NEMO. Conclusions Incontinentia pigmenti is a rare X-linked dominant multisystem disease.It may be misdiagnosed in the initial stages.Except typical clinical features,skin biops y and gene analysis are main evidence for diagnosis.Early detection and interven tion are important for prognosis.

OBJECTIVETo study features of brain gray matter injury in cerebral infarction patients and intervention of scalp acupuncture by using voxel-based morphology.

METHODSA total of 16 cerebral infarction patients were recruited in this study, and assigned to the scalp acupuncture group and the control group, 8 in each group. Another 16 healthy volunteers were recruited as a normal group. All patients received scanning of T1 structure. Images were managed using VBM8 Software package. Difference of the gray matter structure was compared among the scalp acupuncture group, the control group, and the healthy volunteers.

RESULTSCompared with healthy volunteers, gray matter injury of cerebral infarction patients mainly occurred in 14 brain regions such as cingulate gyrus, precuneus, cuneus, anterior central gyrus, insular lobe, and so on. They were mainly distributed in affected side. Two weeks after treatment when compared with healthy volunteers, gray matter injury of cerebral infarction patients in the scalp acupuncture group still existed in 8 brain regions such as bilateral lingual gyrus, posterior cingulate gyrus, left cuneus, right precuneus, and so on. New gray matter injury occurred in lingual gyrus and posterior cingulate gyrus. Two weeks after treatment when compared with healthy volunteers, gray matter injury of cerebral infarction patients in the control group existed in 23 brain regions: bilateral anterior cingulum, caudate nucleus, cuneate lobe, insular lobe, inferior frontal gyrus, medial frontal gyrus, precuneus, paracentral lobule, superior temporal gyrus, middle temporal gyrus, lingual gyrus, right postcentral gyrus, posterior cingulate gyrus, precentral gyrus, middle frontal gyrus, and so on. New gray matter injury still existed in 9 cerebral regions such as lingual gyrus, posterior cingulate gyrus, postcentral gyrus, and so on.

CONCLUSIONSBrain gray matter structure is widely injured after cerebral infarction. Brain gray matter volume gradually decreased as time went by. Combined use of scalp acupuncture might inhibit the progression of gray matter injury more effectively.

Objective To analyze CT findings of insulinoma,and to summarize the causes of missed diagnosis of nontypical insuli-noma.Methods Clinical and CT manifestations of 18 patients with 18 insulinomas were analyzed retrospectively which were proved by surgery and pathology,and the causes of the missed diagnosis of nontypical insulinoma were also summarized.Results 10 patients with 10 insulinoma underwent CT plain scan with isodensity in 9 and slightly lower density in 1 with thread-like capsule.Other 18 patients underwent enhanced CT scan,10 of whom showed obvious enhancement in arterial phase with isodentisy in 6 and slightly higher density in 4 in portal phase,and isodensity in 10 in delayed phase.4 lesions showed mild-to-moderate enhancement in arterial phase with slightly higher density than normal pancreas in 2 and isodentisy in 2 in portal phase,and slightly higher density than nor-mal pancreas in 1 and similar density to pancreas in 3 in delayed phase.In portal phase,the enhanced degree in 8 was similar to the pancreas,and that in 6 was slightly higher or higher than that of pancreas.In delayed phase,13 were similar to the pancreas and other 1 was higher than that.3 of 18 lesions were easily missed,and 4 lesions with missed diagnosis showed isodensity on plain CT and en-hanced CT,and were further detected by other imaging methods.Conclusion Multiphase enhancement CT scanning can be used as the first choice for the insulinoma.

Background and purpose: Because of the aggressive nature of hilar cholangiocarcinoma and the absence of effective adjuvant therapy, surgical radical resection offers hilar cholangiocarcinoma patients the only choice. Research focus include preoperative assessment, the use of preoperative biliary drainage, the range of hepatic resection, and the range of lymphadenectomy. To investigate the clinical experience and efifcacy of combined hepatectomy in the treatment of hilar cholangiocarcinoma. Methods: Two hundred and seven patients with hilar cholangiocarcinoma treated surgically in the First Afifliated Hospital of Kunming Medical University form Jan. 2007 to Oct. 2013 were retrospectively analyzed. Results:Of the 207 patients, 125 patients who received radical resection (R0 resection) and the curative resection rate was 60.4%. One hundred and iffty-six cases were treated in combined hepatectomy group, 51 cases in non-hepatectomy group, the rate of R0 resection was 70.5%in hepatectomy group and 29.4%in non-hepatectomy group, and the difference was signiifcant (P<0.01). Two patients died perioperatively, the main postoperative complications included hepatic function insufifciency and bile leakage. One hundred and seventy-two patients were followed up, the median survival time of the 102 patients who received R0 resection was 45 months, and the 1, 3, 5 year survival rates were 96.1%, 59.1%and 17.2%. The median survival time of the 70 patients who received R1-2 resection was 26 months, and the 1, 3 year survival rates were 81.3%and 19.2%, and none of the patient survived for over 5 years. The survival rate of patients who received R0 resection was signiifcantly higher than those who received R1-2 resection (χ2=39.121, P<0.01). In the hepatectomy group was awarded the R0 resection in patients with postoperative 1, 3, 5 year survival rate was 97.8%, 63.9% and 18.0%, in non-hepatectomy group received R0 resection in patients with postoperative 1, 3, 5 year survival rate was 83.3%, 20.8%and 8.3%. There were signiifcant differences in the postoperative survival rate between both group (χ2=5.988, P=0.014). Conclusion:Radical excision is the key to improve the long term survival. Combined hemihepatectomy and standardized lymph node resection has signiifcantly improved the radical resection rate and the efifcacy of treatment for hilar cholangiocarcinoma.
