Objective To explore the clinical value of MRI in diagnosing and treating cesarean scar pregnancy (CSP).Methods A retrospective analysis was conducted on the clinical manifestations of 54 patients diagnosed with CSP between January 2009 to January 2013 in Peking University Third Hospital.Based on the patients' MRI image and other clinical datas,we did transvaginal operation on patients with CSP1,and transvaginal combined with abdominal operations on patients with CSP2.The intraoperative blood loss,operation time,postoperative hospital stay,and the length of time required for of serum hCG dropping to normal of the patients were analyzed.Results The average age of the 54 patients was (34±5) years and the average duration of gestation was (56± 16) days,all patients' vital sign were stable,the hCG level was 23-142 962 U/L before treatment.Twelve patients were diagnosed with CSP1 by MRI,and 5 of them had focus of 1-2 cm in diameter,the 5 patients' serum hCG level was 436-1 159 U/L and 23-32 days after drug administration,their hCG level returned to normal; the other 7 patients had focus of 2.0-4.4 cm in diameter,and their hCG level was 2 218-63 446 U/L,lesion resection was done on the 7 patients by hysteroscope or under B-uhrasound monitor.Forty-two patients were diagnosed with CSP2,and their focus were 1.0-7.1 cm in diameter,and serum hCG level were 23-142 962 U/L.We did bilateral uterine artery occlusion by laparoscope or laparotomy during operation for 22 patients or bilateral uterine artery embolization (UAE) before operation for 20 patients,then we did lesion resections.The blood loss during operation of CSP1 or CSP 2 was 50.1,267.2 ml; operation time was 30,128 minutes; postoperative hospital stay was 4.6,6.7 days;their serum hCG returned to normal 13-30 days after the surgery.All the 54 patients' uterus were preserved,and the patients undergoing operations were all cured without the second operation.Conclusion MRI is an effective method to conduct clinical treatment in CSP.

Objective To explore the value of diffusion tensor imaging (DTI) and diffusion tensor tracography (DTT) in assessment of Corticospinal tract (CST) and medial lemniscus (ML) in tumors involving brainstem.Methods A total of 35 cases with pathologically confirmed tumors involving brainstem were collected,and 35 volunteers matched with genders and ages were recruited as the normal group.DTI scanning was performed on all the patients and controls.The damage degrees of CST and ML were evaluated and graded by DTT,and the dysfunction degrees were evaluated for the patients.Spearman correlation was used to statistically analyze the relationships of limb movement,sensory dysfunction and CST and ML damage.Results According to the rating results,normal findings,shifting,edema or infiltration and damage of CST was found in 9,9,11,and 6 cases respectively.They were 8,9,15,3 cases for ML.Motor function was normal in 20 cases,slightly defective in 11 cases,and moderate defective in 4 cases.Sensory function was normal in 21 cases,slightly defective in 6 cases,and moderate defective in 8 cases.The patients' dyskinesia and CST damage degree,sensory dysfunction and ML damage degree were positively correlated (r was 0.786 and 0.686 respectively,P ＜ 0.01).The position relationship among tumor and CST and ML could be well displayed on images.None of the patients showed new symptoms of dysneuria after surgery.Conclusions DTI and DTT technology can be used to evaluate CST and ML damage degree in tumors involving brainstem.They can display the position relationship between tumor and the brainstem CST and ML,which is important in protecting the brainstem fiber tract during operation and evaluating the recovery after the operation.

Objective To observe the clinical effect of conservative therapy on prolapse of lumbar intervertebral disc(PLID).Methods 365 PID patients included 78 acute cases and 287 subacute cases.The treating principle for acute cases was eliminating edema and aseptic inflammation,and that for subacute cases was releasing adhesion and removing inflammatory stimulation to nerve root.Results Of 78 acute patients,60 cases(76.9%) healed,18 cases(23.1%) improved;of 287 subacute patients,186 cases(64.8%) healed,101 cases(35.2%) improved,the effective rate of 365 patients was 99.7%.Conclusion Conservative therapy is effect on PLID at acute and subacute periods.

Objective To observe the effect of inferior vena cava filter (IVCF) on prevention of bone cement implantation syndrome (BCIS). Methods Ten sheep were divided into 2 even groups, BCIS and LVCF intervention ones. First IVCF was implanted into the inferior vena cava through cervical vena-right atrium pathway under fluoroscopic monitoring to observe the influence of IVCF on BCIS. Then BCIS was es-tablished in the same sheep by compressing 10 mL of bone cement into a sheep medullary canal after mutilation of the left femur. Arterial blood pressure, heart rate, central venous pressure (CVP) and blood gas were monitored, while an ultrasonic device was utilized to monitor fat embolisms in the right atriums of the sheep. Oil red staining was performed to detect fat embolisms in pulmonary arteries after the sheep were executed. Results In BCIS group, dotted uneven resonances were found in the right atrium and right ventricle when the medullary canal pressure was increased to 120 mm Hg, indicating embolisms in the right chambers. The dotted resonances were increased to ponderous, snowflake-like ones as the medullary canal pressure climbed up. At the same time, blood pressure and Pa02 dropped significantly, the systolic blood pressure dropped to (80±11) mm Hg and PaO<.2> to the minimum 25 minutes after cone cement implantation. The heart rate and CVP increased continuously. The blood gas assay indicated respiratory and metabolic acidosis. The oil red staining showed bulk fat embolus in pulmonary arteries. But in IVCF group, the similar resonances were not observed throughout the surgery and the medullary canal pressure climbed to 400 mm Hg, reaching the maximum of our pressure gage range. The blood pressure, PaO2, heart rate and CVP did not change much compared to those before implantation. The blood gas and pulmonary oil red staining showed few changes either. Conclusion IVCF implantation can prevent the genesis of BCIS.

Objective To confirm the distribution of high arsenic drinking water and the situation of endemic arsenism in Hubei Province, to provide reference basis for prevention and control of endemic arsenic disease. Methods Using typical investigation and sample investigation in 2006 and 2007, the arsenic content of water was detected sampled from 19 counties(cities or communities). And those water samples which were close to or exceeded the stipulated standard were rechecked by the national standard method. Furthermore, the situation of endemic arsenism was investigated in the cities having high arsenic contents of water. Results In 2006,10 028 water samples of 446 villages in 6 counties (cities or communities) were tested, the wells of high arsenic (> 0.05 mg/L) were found in 5 counties (cities or communities) and the proportion of the well that exceeded stipulated standard was 5.29%(530/10 028); In 2007,19 086 water samples of 1282 villages in 17 counties(cities or communities) were tested, the wells of high arsenic were found in 11 counties(cities or communities), and the proportion of the well that exceeded stipulated standard was 1.74%(333/19 086). In these two years, 29 114 water samples were tested, in which 863 water samples were exceeding the stipulated standard. The 2.96% of total wells exceeded stipulated standard and mainly distributed in 179 villages of 12 counties(cities or communities). And the highest arsenic content of water sample was 2.012 mg/L. In the endemic arsenism area, 2 critical, 1 moderate and 1 mild arsenism patients had been found. Conclusions The water of high arsenic content are scattered in Hubei Province and the situation of endemic arsenism disease is mild. Improving water aiming at decreasing arsenic and establishing patient files should be carried out immediately.

Intracerebral hemorrhage (ICH) is a fatal stroke with high morbidity and mortality.Nearly 1/3 patients with ICH suffer from hematoma expansion (HE),which is directly related to the prognosis.Therefore,the early prediction of HE has important guiding significance for the therapeutic intervention.At present,more and more imaging signs have been found to predict HE,such as CTA points,CTA leakage signs,and CT perfusion dynamic signs.However,non-enhanced CT (NCCT) is widely used as a gold standard for the diagnosis of ICH.Recently,several signs of NCCT have been found,including swirling sign,blend sign,black hole sign,hypodensities in hematoma,island sign and satellite sign.

OBJECTIVETo evaluate the clinical value of laparoscopy-assisted modified Soave procedure for Hirschsprung disease in adults.

METHODSTwenty-eight patients with a preoperative diagnosis of Hirschsprung disease underwent laparoscopy-assisted modified Soave procedure between March 2005 and December 2009. Clinical data were retrospectively analyzed.

RESULTSThere were no conversions to open surgery. The mean operative time was (165±12) minutes (range: 135-185 minutes). Estimated blood loss ranged from 50 to 250 ml, and no patients required intraoperative blood transfusion. Postoperative pathologic examination showed Hirschsprung diseases in 19 patients and Hirschsprung allied diseases in 9. Only two patients developed rectal cuff infection and three mild seepage. Other patients had no postoperative complications. The mean hospital stay was (17.5±1.0) days. No fecal incontinence or recurrent constipation occurred during follow-up.

CONCLUSIONLaparoscopy- assisted modified Soave procedure is safe and effective for Hirschsprung disease.

OBJECTIVETo study the clinical characteristics, diagnosis, treatment and prognostic factors of gastrointestinal stromal tumor(GIST).

METHODSClinicopathological data of 217 GIST patients from January 2005 to September 2010 in Wuhan Union Hospital were analyzed retrospectively and the prognostic factors were evaluated.

RESULTSThere were 103 males and 114 females with a median age of 55 years old. Two hundred and thirteen patients underwent R0 resection and 4 R1 resection due to extensive invasion. Thirty-five patients underwent laparoscopic resection. Forty-eight patients received imatinib mesylate therapy after surgery. A total of 178 patients(82.0%) were followed up for 3 to 74 months. Sixteen patients(9.0%) developed recurrence or metastasis. Logistic regression analysis showed that tumor location (OR=2.547, 95% CI:1.466-4.424) and mitotic count(OR=6.556, 95% CI:2.974-14.449) were independent factors for post-operative recurrence or metastasis. Five patients survived with tumor, and 11 patients(6.2%) died of GIST including intestinal GIST(n=7) and extraintestinal GIST(n=4). Cox regression analysis showed that the mitotic count (RR=2.654, 95% CI:1.094-6.438) and post-operative recurrence or metastasis (RR=32.988, 95% CI:3.879-280.529) were independent prognostic factors.

CONCLUSIONSTumor location and mitotic count are independent risk factors for post-operative recurrence or metastasis in GIST. Mitotic count and post-operative recurrence or metastasis are independent indicators of poor prognosis. Surgical radical resection combined with targeted therapy can achieve satisfactory outcomes in patients with GIST.

OBJECTIVETo explore a better therapy for knee osteoarthritis.

METHODSOne hundred cases were randomly divided into a comprehensive group and an acupuncture group, 50 cases in each one. The comprehensive treatment of fire needles at bones combined with cupping and Tuina on local area of affected knee was applied in the comprehensive group. The Ashi points were mainly selected in the fire needles at bones therapy, once every other day. The cupping and Tuina therapy was adopted once a day. The conventional acupuncture was applied in the acupuncture group, in which Dubi (ST 35), Neixiyan (EX-LE 4), Xuehai (SP 10), Liangqiu (ST 34) and so on were selected, once a day. Ten days of treatment were taken as a treatment course in both two groups, and totally 1 to 2 courses was required. The pain score of joint before and after the treatment was observed and efficacy was assessed in two groups.

RESULTSCompared before the treatment, the pain score of joint after the treatment was obviously improved in two groups (both P<0.05), and the score in the comprehensive group was lower than that in the acupuncture group (P<0.05). The clinical cured rate was 38.0% (19/50), which was superior to 20.0% (10/50) in the acupuncture group.

CONCLUSIONThe comprehensive treatment of fire needles at bones combined with cupping and Tuina, considered as a better therapy for knee osteoarthritis, could improve joint pain, swelling and action function, which is superior to the conventional acupuncture.
