人体体模检测多层螺旋CT低剂量胸-腹部联合扫描剂量研究

目的利用人体仿真体模来测量选择不同曝光剂量在胸-腹部联合扫描中实质器官的吸收剂量及辐射剂量评估。方法对京都科学生产的X线/CT全身可动体模PH2B进行低剂量胸-腹部联合扫描,以管电压120kV,固定管电流400mA组为对照组,相同管电压条件下,低剂量组为实验组,管电流分别为240、200、160、120、80、60、40mA,记录每组扫描方案CT扫描自动生成体模X线剂量参数,包括CT容积剂量指数(CTDIvol)、剂量长度乘积(DLP)、有效剂量(ED)及图像质量客观评价指标图像噪声值(SD)、对比噪声比(CNR);采用SPSS22.0统计软件,以常规剂量与七组低剂量CT扫描的图片质量、辐射剂量进行比较,采用独立样本t检验,以P<0.05为差异有统计学意义;计量资料多组间比较采用ANOVA分析,进一步两两比较采用Dunnett-t检验;主观评分资料为非正态分布的定量资料,多组间主观评分资料的比较采用Kruskal?Wallis秩和检验,进一步两两比较采用Mann-WhitneyU检验。结果人体仿真体模胸腹部主要脏器与正常人体CT图像相似。肝脏平均CT值差异有统计学意义(P<0.05),肺、心脏、脊柱及肾脏平均CT值与人体差异无统计学意义(P>0.05)。实验组分别较对照组毫安量降低40%、50%、60%、70%、80%、85%、90%,均属于低剂量扫描;随着mA值逐渐降低,CT容积剂量指数(CTDIvol)、剂量长度乘积(DLP)、有效剂量(ED)均随之下降。图像噪声(SD)随着mA值减小而增大,肺、心、肝、骨的图像噪声差异均有统计学意义(P<0.001)。对比噪声比(CNR)随着mA值减小而降低,肺、心、肝、骨的图像对比噪声比差异均有统计学意义(P<0.001)。三名医师分别对不同组别的肺、心脏、肝脏、骨骼的评分差异均有统计学意义(P<0.05)。结论胸-腹部联合“一站式”低剂量扫描技术可确保图像质量同时降低辐射剂量,管电压为120kV时,降低管电流为240、200mA,显示胸腹部脏器较好。

Hepatic hydrothorax occurring rapidly after manual abdominal compression

Hepatic hydrothorax is a relatively infrequent but po- tentially serious complication of liver cirrhosis that often causes respiratory dysfunction. Several hypotheses for the development of hepatic hydrothorax have been sug- gested to explain a transdiaphragmatic shift of ascitic fluid through small defects between the peritoneal cavity and the pleural space. However, the rapid development of hydrothorax within several hours is seldom encoun- tered. In addition, the causal factors for rapid passage of ascitic fluid into the pleural cavity are unknown. This report describes a patient with liver cirrhosis who suf- fered rapid development of a hydrothorax after manual compression of the abdomen.

The new species can be distinguished from the other species of genus Nerocila by its endopod of uropods with deep notch, sharply serrated on the lateral margin and strongly serrated on the medial margin; antennule with 1st article swollen; dactyli of pereopods I, II, IV, V swollen.

Clinical study on abdominal acupuncture plus plum-blossom needle tapping for primary insomnia

Objective： To investigate the clinical efficacy and action mechanism of abdominal acupuncture plus plum-blossom needle tapping for primary insomnia. Methods： A total of 66 eligible cases were randomly allocated into an observation group（n=33） and a control group（n=33）. Cases in the observation group received abdominal acupuncture plus plum-blossom needle tapping, whereas cases in the control group received abdominal acupuncture alone. After 2, 6 weeks of treatment and 4 weeks after end of treatment, the patients in both groups were evaluated using the Pittsburgh sleep quality index（PSQI） and measure your medical outcome profile（MYMOP） based on the patients＇ self-report. Results： After 2 weeks of treatment, the total effective rate was 90.9% in the observation group, versus 63.6% in the control group, showing a statistical difference（P〈0.05）. After 6 weeks of treatment, there were no between-group statistical differences in total effective rate（P〈0.05）. After 6 weeks, the sleep quality and efficiency scores in the observation group were better than those in the control group. Four weeks after end of treatment, the scores of sleep quality and MYMOP in the observation group were better than those in the control group（P〈0.05）. Conclusion： Abdominal acupuncture plus plum-blossom needle tapping can obtain fast, accurate effect for primary insomnia and improve patients＇ sleep quality and efficiency.

Thoracic spinal trauma associated with closed thoraco-abdominal injury

Objective: To explore the management of thoracic spinal trauma (TST) associated with closed thoraco abdominal injuries (CTAI). Methods: A retrospective study was made on 259 patients with TST admitted to our department as an emergency treatment from January 1996 to June 2001. We summarized the clinical features of TST associated with CTAI. Results: Among 259 patients with thoracic spinal trauma, 112 were associated with CTAI. Traffic accident was the most common cause. The force causing upper TST was more violent than that causing the lower. Pulmonary complications were the leading cause of death in this group. Surgery could not improve neurological function for completely paraplegic patients. Conclusions: The reason that upper TST has the tendency to be associated with CTAI is its special anatomical feature. Routine ultrasonic examination can avoid misdiagnosis of latent closed abdominal injuries associated with spinal injury. The presence of potential injuries, especially CTAI, should be considered when deciding whether or not to perform surgery early.

Observation on therapeutic effect of acupuncture at abdomen acupoints plus tuina for lumbar intervertebral disc herniation

Objective: To observe the clinical efficacy of acupuncture at abdomen acupoints plus tuina for lumbar intervertebral disc herniation (LIDH). Methods: A total of 70 patients with LIDH were randomized into an observation group and a control group, with 35 cases in each group. The observation group was treated with acupuncture at abdomen acupoints plus tuina, while the control group was treated only with tuina treatment. The clinical efficacy was observed after one course of treatment. Results: The cure rate and the total effective rate of the observation group were 83.3% and 96.7%, respectively. The cure rate and the total effective rate of the control group were 39.4% and 78.8%, respectively. There were significant differences in the cured rate and the total effective rate between the two groups (both P<0.05). There was no significant differenee in Japanese Orthopedic Association (JOA) score between the two groups before treatment (P>0.05). After treatment, the JOA scores of both groups in creased sign ifica ntly, and the in tra-group differe nces were statistically sign ifica nt (both P<0.05);the JOA score of the observation group was significantly higher than that of the control group (P<0.05). Conclusion: Acupuncture at abdomen acupoints plus tuina has a better therapeutic effect than tuina alone in the treatment of LIDH.

Polytrauma with thoracic and/or abdominal injuries: experience in 1 540 cases

Objective ：To investigate the early diagnosis and treatment of polytrauma patients with thoracic and/or abdominal injuries. Methods： The data of all polytrauma patients with thoracic and/or abdominal injuries during the past 10 years were studied retrospectively. Results： In the present study, there were 1 540 polytrauma patients, accounting for 65.0% of all 2 368 trauma patients. Of these patients, 62.4% were in shock state on admission. The operative rates were 15.0% （181/1 206） and 79.9% （ 612/766 ） in patients with thoracic and abdominal injury （ P 〈 0.01 ）, 5.2 % （39/758） and 31.7% （142/448） in patients with blunt and penetrating chest trauma （P〈0.01）, and 72.4% （359/496） and 93.7 % （253/270） in patients with blunt and penetrating abdominal injuries （P〈0.01）, respectively. To deal with abdominal injury, angioembolization was performed in 43 cases, with 42 cured. The overall mortality rate was 6.2%. And in the blunt and penetrating subgroups, the mortalities were 7.9 % （75/950） and 3.6 % （21/590）, respectively （P〈0.01）. Most patients died from exsanguination. Conclusions： The first ＂golden hour＂ after trauma should be grasped, since the treatment in this hour can determine greatly whether the critically-injured victim could survive. Prompt diagnosis and proper treatment contribute more greatly to the survival of the victim than the severity of injury.

Warm needling moxibustion versus electroacupuncture for simple obesity due to yang deficiency of the spleen and kidney: a controlled clinical trial

Objective: To compare the therapeutic efficacy between warm needling moxibustion and electroacupuncture (EA) in the treatment of simple obesity due to yang deficiency of the spleen and kidney. Methods: Seventy patients with simple obesity due to yang deficiency of the spleen and kidney were randomly divided into a warm needling moxibustion group and an EA group, with 35 subjects in each group. Same major acupoints were selected for the two groups, including Shuifen (CV 9), Guanyuan (CV 4), Daheng (SP 15), Shuidao (ST 28), Shousanli (LI 10), Zusanli (ST 36), Sanyinjiao (SP 6) and Taixi (KI 3). The warm needling moxibustion group received warm needling moxibustion, while the EA group received EA treatment. The interventions were performed once every other day, with 15 treatments as one course. The therapeutic efficacy, body weight and body mass index (BMI) were then observed and compared. Results: The total effective rate in the warm needling moxibustion group was 85.7% versus 77.1% in the EA group, and the between-group difference was statistically significant (P<0.05). The warm needling moxibustion was remarkably superior to the EA in weight loss and lowering BMI, both with statistical significance (P<0.05, P<0.01). At the three-month follow-up, the body weight and BMI further decreased in the warm needling moxibustion group (both P<0.05), and the levels were lower than those in the EA group (P<0.05, P<0.01). Conclusion: Warm needling moxibustion can produce reliable and consistent efficacy in the treatment of simple obesity due to yang deficiency of the spleen and kidney. Compared with EA, warm needling moxibustion shows advantage in both short-term and long-term efficacies, and thus is worth promotion in clinical practice.

Clinical analysis of craniocerebral trauma complicated with thoracoabdominal injuries in 2165 cases

Objective: To explore the optimal treatment for craniocerebral trauma complicated with thoraco-abdominal injuries. Methods: A total of 2 165 cases of craniocerebral trauma complicated with thoraco-abdominal injuries admitted to our hospital between July 1993 and June 2003 were retrospectively studied. Among them, 382 cases sustained severe craniocerebral trauma (in which 167 were complicated with shock), 733 thoracic injuries, 645 abdominal injuries and 787 thoraco-abdominal injuries. On admittance, 294 cases had developed shock. With the prime goal of saving life, respiratory and circulatory systems and encephalothilipsis were especially treated and monitored. Priority in management was directed to severe or open injures rather than to moderate or closed injures. For cases with cerebral hernia due to intracranial hematoma and severe shock due to blood loss, cerebral hernia and shock were treated concurrently. Results: After treatment, 2024 ( 93.49%) cases survived and the other 141 ( 6.51%) died. Among patients who had severe craniocerebral injury with shock and those without, 78 ( 46.71%) and 53 ( 24.56%) died, respectively. For patients who had underwent craniocerebral and thoraco-abdominal operations concurrently and those who had not, the death rates were 58.49%- 65.96% and 28.57% respectively, indicating a significant difference (P< 0.05). Conclusions: Treatment for hematoma hernia, shock and disturbed respiration is the key in the management of multiple trauma of craniocerebral, thoracic or abdominal injuries, especially when two or three conditions occurred simultaneously. Unless it is necessary, operations at two different parts at the same time is not recommended. It is preferred to start two concurrent operations at different time.

Therapeutic observation on tuina at head and abdomen for headache due to phlegm turbidity

Objective:To observe the clinical efficacy of tuina at head and abdomen for headache due to phlegm turbidity.Methods:A total of 56 patients with headache due to phlegm turbidity were randomized into a tuina group and a Chinese medicine group by the random number table,with 28 cases in each group.The tuina group was treated mainly with tuina at the head and abdomen,while the Chinese medicine group was treated with oral administration of Ban Xia Bai Zhu Tian Ma Tang(Pinellio,Atractylodes Mocrocepholo and Gastrodio Decoction).The course of treatment was 30 d.The scores of headache index,traditional Chinese medicine syndrome scale,and the therapeutic efficacy were observed.Results:There were 2 dropouts in each group during treatment.The total effective rate was 92.3%in the tuina group,significantly higher than 76.9%in the Chinese medicine group(P<0.05).The scores of headache index and traditional Chinese medicine syndrome scale in both groups decreased after treatment(both P<0.05),and scores in the tuina group were lower than those in the Chinese medicine group(both P<0.05).Conclusion:Tuina mainly at head and abdomen is effective in treating headache due to phlegm turbidity,and has a better effect than Ban Xia Bai Zhu Tian Ma Tang(Pinellia,Atractylodes Macrocephalo and Gastrodio Decoction).

Management of multiple trauma with mainly thoracic and abdominal injuries： a report of 1166 cases

Objective： To discuss the diagnosis and treatment of multiple trauma with mainly thoracic and abdominal injuries. Methods： A retrospective analysis was performed on data of multiple trauma cases with mainly thoracic and/or abdominal injuries. Results： Of 1166 cases, 72.3% were found with shock. The operation rates of thoracic and abdominal injuries were 14.8% （119/804） and 83.5% （710/850） respectively （ x^2=780.683, P 〈0.01）. The operation rates of blunt and penetrating thoracic injuries was 6.8% （42/617） and 40.6% （76/187） respectively （ x^2=131.701, P〈0.01）. The operation rates of blunt and penetrating abdominal injuries were 77.1% （434/563） and 96.1% （276/287） respectively （ x^2=50.302, P〈0.01）. The operation rates of blunt thoracio-abdominal injuries were 6.8% （42/617） in thoracic region and 77.1% （434/563） in abdomen respectively （x^2=544.043, P〈0.01 ）. Among the cases of abdominal injuries, 41 received arteriography embolism, with the efficacy of 95.1% （39/41）. Total mortality rate was 6.1%. The mortality rates of blunt and penetrating injuries were 7.3% （62/854） and 2.9% （9/312） （ x^2=6.51, P〈0.005）. The deaths were mainly due to large volume of blood loss. Conclusions： When both thoracic and abdominal injuries exist, laparotomy is frequently required rather than thoracotomy. Laparotomy is seldomly used for blunt thoracic injuries, but usually used for penetrating thoracic and abdominal injuries. Mortality rate of penetrating thoracic and abdominal injuries is markedly lower than that of blunt injuries. Surgical operation is still important for those patients with penetrating thoracic or abdominal injuries.
