Objective To investigate the application value of minimally-invasive surgical treatment in patients with traumatic epidural hematoma(EDH)straddling transverse sinus.Methods Forty-eight patients with traumatic EDH straddling transverse sinus were chosen and preoperative Glasgow Coma Scale (GCS)score ≥8 scores were managed with minimally-invasive drainage under CT location.CT scanning was performed 1 h,3 d after operation and hematoma volume was calculated,and Glasgow Outcome Scale(GOS)score was evaluated 3 months after operation.Results CT scanning showed that the hematoma volume preoperative was(46 ± 14)ml,postoperative of 1 h was(21 ± 4)ml,and 3 d was(16 ± 3)ml,decreased more obviously than preoperative,and there was significant difference(P ＜ 0.05).The GCS score preoperative was(8 ± 4)scores,postoperative of 3 d was(12 ± 2)scores,increased more obviously than preoperative,and there was significant difference(P ＜ 0.05).Three months after operation in 48 patients,GOS score 5 points 37 cases(77.1％,37/48),4 points 7 cases(14.6％,7/48),2 points 2 cases(4.2％,2/48),1 point two cases(4.2％,2/48).Conclusion Minimally-invasive drainage is effective in the treatment of traumatic EDH straddling transverse sinus with GCS score ≥ 8 scores.

Objective To observe the variations and distribution of the pulmonary fissures of normal subjects in China on multi-planar recontruction (MPR) images of 64- slice helical CT.Methods A total of 1235 subiects underwent 64- slice helical CT scan with a slice thickness of 0.6 mm.The MPR images were observed to find normal interlobar fissures and the variations including the accessory fissures occurred in lobar or segmental lungs.Results Of the all cases,no variation was seen in 80.08%(989/1235),and pulmonary fissure variations occurred in the remaining 19.92%(246/1235).Among pulmonary fissure variations,20.33% (50 cases) occurred bilaterally,with the other 79.67%(196 cases) unilaterally.Of the unilateral pulmonary fissure variations,63.01%(155 cases) was seen in right lungs,and 16.66% (41 cases)was found in left lungs.There was neither oblique nor horizontal fissure in 1.22%(3 cases) of right lungs.Absence of oblique fissure happened more frequently in left lungs (6.91%,17 cases) than right lungs(3.65%,9 cases).Incomplete oblique fissure happened more frequently in left lungs (8.53%,21 cases)than in right lungs(4.06%,10 cases).Totally,absence of the horizontal fissures were found in 27.24%(67 cases) of the subjects,and incomplete horizontal fissures were found in 9.76% (24 cases).Accessory fissure were found in 83.33%(205 cases) of the subjects,and they happened more frequently in right lungs than in left lungs(53.66%,132 cases on the right,while 29.67%,73 cases on the left).Accessory fissures on right lower lobe and segments happened much more than on the left(40.65%,100 cases on the right,while 7.72%.19 cases on the left).Lingular fissures in the lungs were found in 15.85%(39 cases).The changes in shape and location of the oblique and horizontal fissures were found in 41.06%(101 cases),and happened more frequently in right lungs than left lungs (35.37%,87 cases on the right,5.69%,14 cases on the left).Conclusions Sixty-four-slice helical CT with MPR can clearly display pulmonary fissures and their variations,and it can distinguished small lesions from small vessels.

Basic research and clinical research on multiple myeloma (MM) have extensively progressed, as proven by the change in the definition of complete response (CR). With improvements in laboratory technology and introduction of novel agents, CR particu-larly emphasized both micro-and macro-models. The development of CR yielded therapeutic advances in MM and vice versa. The defi-nitions of response and treatment strategies were closely connected and improved. A need exists for further detailed studies on long-term disease control, such as optimal combination of agents. Given the shortage of new drugs and the distinctiveness of health in-surance, Chinese doctors should select the best treatment projects based on real-life situation in China.

Objective To study the feasibility and morphological characteristics of wide caliber of local biliary tract constructed by increasing pressure of local bile duct in a short period of time.Methods Twelve mongrel dogs were randomized into 2 groups.In group A,only inlaid bile duct dilator(IBDD)was placed for biliary drainage in common bile duct.In group B,IBDD was placed in tommort bile duct for biliary drainage and dilated it through affusing 0.1 ml,0.1 5 ml,0.2 ml and 0.25 ml water on postoperative day 1,8,15 and 22,respectively.The expandable ballbladders were kept on being dilated with increasing pressure for a month.Total bilirubin(TB),alanine aminotransferase (ALT),aspartate aminotransferase;aspartate transaminase(AST)of serum,bile duct diameter (BDD),histologic changes of biliary duct wall and hepatic tissue,and postoperative biliary tract contrast were determined before and after operation in both groups.Results There was no significant difference in TB,ALT,AST and histologic changes of hepatic tissue in bilary predilation and postdilation of each group and between group A and group B.There was great difference in BDD in bilary predilation and postdilation of each group and between group A and group B.In group B,the biliary wall was thickened and the lumina of bile duct widened,favorable tenacity of broaden biliary tract was shown.The specific staining of the broadened biliary wall showed that collagen and elastic fibers compacted fine and close and there was no breakage.Conclusion Dilated local bile duct constructed by increasing internal pressure of local bile duct has thick wall,wide caliber and its collagen and elastic fibers compact fine and close.This provides condition to supply early-stage cholangio-jejunostomotic reconstruction of bile duct iniury and create wide stoma for cholangio-jejunostomy in dogs.

we examined the serum copper level in 125 pregnant women (83) normal pregnant women of 28～40 weeks of pregnancy; 12 patients with se-vere edema-proteinurine-hyperterision syndromeduring 37～40 weeks of pregnancy; 30 patientswith prolonged pregnancy) and compared it withurine E/C value and Apgar score in order to deter-mine the reliability of serum copper value in diag-nosing placental insufficiency. The results con-firmed that the serum copper value was increasingwith the growth of weeks of pregnancy, but it wasdecreasing after the fortieth week of pregnancy.Comparison of the serum copper value with theurine E/C value showed that when the E/C or = 10. And when the Apgar score7. These results indicatethat the serum copper value can serve as an indexof placental function in the third trimester of preg-nancy.

Objective To study the curative effect of posterior diskoscope discectomy for adolescent lumbar disc herniation.Methods Eleven adolescent patients with lumbar disc herniation were treated with posterior diskoseope discectomy,the Japanese orthopaedic association (JOA) lower back pain score was observed and compared before operation and after operation 3,6,12 months.Results The JOA lower back pain score were (15.45 ± 2.73),(27.18 ± 2.08),(28.18 ± 1.25),(28.54 ± 1.21) scores before operation and after operation 3,6,12 months,there was statistical difference in JOA lower back pain score between before operation and after operation 3,6,12 months (P ＜ 0.01).The patients were followed up for 1-10 years,mean 7.9 years,excellent was in 8 cases,good was in 2 cases,general was in 1 case.Recurrence and iatrogenic lumbar instability were not found.Conclusions The posterior diskoscope discectomy with less trauma,less bleeding,faster recovery,and can achieve the same decompression objective with the traditional open surgical.So posterior diskoscope discectomy can be used as adolescent treatment of lumbar disc herniation.

Objective To observe the efficacy of high-energy red light combined with human-like collagen dressing in treatment of facial corticosteroid addictive dermatitis.Methods Eighty-three patients with facial corticosteroid addictive dermatitis were divided into treatment group (42 cases) and control group (41 cases) by random digits table method.All patients in 2 groups were treated with ebastine 10 mg,once a day,and vitamin E cream,twice a day.At the same time,the patients in control group were given human-like collagen dressing,once a day in the first week,then 3 times/week.On the basis of control treatment,the patients in treatment group were irradiated with high-energy red light 10 min in face,2-3 times/week.The treatment of both groups lasted for 12 weeks.The symptoms,skin lesions and untoward reaction were observed after treatment of 4,8 and 12 weeks.Results After treatment of 4 weeks,there was no statistical difference in the effective rate between 2 groups (P ＞ 0.05).After treatment of 8 and 12 weeks,the effective rates in treatment group were significantly higher than those in control group [83.3％(35/42) vs.58.5％ (24/41),90.5％ (38/42) vs.65.9％ (27/41)],there were statistical differences (P ＜ 0.05).No untoward reaction was found in 2 groups.Conclusion High-energy red light combined with human-like collagen dressing is effective and safe in treatment of facial corticosteroid addictive dermatitis.

Objective To summarize the imaging features of intra-pancreatic accessory spleen (IPAS)with multidetector computed tomography (MDCT) and improve the awareness and correct diagnosis of IPAS.Methods MDCT images of seven consecutive patients with surgically and pathologically confirmed IPAS were reviewed retrospectively.The investigated features included the location,size,shape,margin,density,and enhancement of the lesions.Results Four patients were male and three were female with a mean age of 49 years old.All the lesions were located at the dorsal side of parenchyma under the capsule of pancreatic tail.Three lesions were in round-like shape,and 4 in oval shape and all were well-defined.All the lesions were mass-like without necrosis and calcification.The maximum diameter of lesion ranged from 0.9 ～ 1.8 cm with a mean value of 1.4 cm.Compared with pancreatic parenchyma,the density of lesions were homogeneous on unenhanced CT,in arterial phase,slightly increased heterogeneous density was observed in 3 patients,slightly increased homogeneous density was observed in 4 patients.All the lesions appeared as slightly increased homogeneous density in portal phase.The CT value in unenhanced phase ranged from 50 ～ 61 Hu with a mean number of 55 Hu; and it ranged from 80 ～ 110 Hu with a mean number of 97 Hu in arterial phase; and the corresponding value was from 99 ～ 120 Hu with a mean number of 102 Hu in portal phase.Among the three patients underwent MDCT angiography,neither artery nor vein was compressed or invaded,and there was no vessel connected with lesions.Conclusions IPAS has some MDCT characteristics.For small solid mass in pancreatic tail,if the density and enhancement pattern is similar to that of spleen,the diagnosis of IPAS should be considered.

Objective To explore the risk factors for hepatitis B virus (HBV) intrauterine infection to provide a scientific ev idence for itsprevention.Methods Three hundred and twelve pregnant women of HBsAg positive screened from April 2013 to May 2015 served as the research subjects and were followed up until 6 months after birth.The infantile mothers of HBsAg and/or HBV DNA positive were selected as the intrauterine infection case group,while other mothers served as the control group.The Logistic regression analysis was adopted to analyze the risk factors for intrauterine HBV infection.The questionnaire survey method was used to collect the basic data and time-resolved immunofluorescence assay was used to detect HBsAg.PCR was adopted to measure level of HBV DNA and automatic biochemistry analyzer was used to measure the hepatic functional parameters including ALT,AST,triglyceride and cholesterol.Results The single factor analysis results indicated that HBeAg,HBV DNA,contamination of amniotic fluid and sexual behavior during pregnancy were related to HBV intrauterine infection(P＜0.05).The multiple variate Logistic regression results showed that positive HBeAg(OR=2.76,95 ％ CI=1.19-7.94),positive HBV DNA(OR=9.62,95 ％ CI=2.58-35.33),and sexual behaviors during pregnancy (OR =1.53,95 ％ CI =1.07-6.40) were the risk factors for intrauterine HBV infection.Conclusion Pregnant women with positive HBeAg,positive HBV DNA and sexual behavior during pregnancy may be the high risk factors for neonatal intrauterine HBV infection.
