OBJECTIVETo study modified ilioinguinal approach through the retrospective analysis on the surgical treatment of 63 patients with pelvic and acetabular fractures through anterior approach.

METHODSFrom January 2006 to January 2013, 63 patients with pelvic and acetabular fractures were treated with the ilioinguinal anterior approach, including 45 males and 18 females, ranging in age from 12 to 68 years old, with an average of (37.71 +/- 13.41) years old. All the patients were divided into two groups: standard ilioinguinal anterior approach group (group A) and modified ilioinguinal anterior approach group(group B). In group A, there were 26 males and 11 females, with an average age of (38.49 +/- 13.64) years old. In group B, there were 19 males and 7 females, with an average age of (36.62 +/- 13.29) years old. Intraoperative and postoperative indicators in group A and B were observed and compared, including operation incision exposure time (from skin incision to complete the ilioinguinal in front of three "windows"), the blood loss, incision close time and treatment effect of Majeed function score.

RESULTSCompared to group A, the incision exposure time of patients in group B was shorter, the blood loss (bleeding during exposure process) was less, and the close incision time was shorter, but the treatment effect of Majeed function score had no significant differences between two groups. All the patients were followed up, and the during ranged from 3 to 36 months, with an average of (18.6 +/- 9.2) months. According to Matta standard assessment reduction of pelvic and acetabular fracture, there were 28 patients got an excellent result, 8 good, and 1 fair in the group A; and 20 patients got an excellent result, 5 good, and 1 fair in the group B. According to Majeed function score for hip function, 20 patients got a satisfactory result, 12 good,4 fair and 1 poor in group A, and the mean score was 82.51 +/- 9.72; and 13 patients got an satisfactory result, 10 good, 3 fair and 0 poor in group B, and the mean score was 80.54 +/- 10.79.

CONCLUSIONThe modified approach has several advantages as follows: providing a good surgical exposure; preventing from the injury of femoral nerve, femoral artery and vein under the inguinal ligament; not needing to open the inguinal canal, which can avoid the occurrence of inguinal hernia, reduce operation prodedures and shorten operation time.

Objective: To investigate the effect of moxibustion at Shenque (CV 8) on fatigue in rats with chronic exercise-induced exhaustion. Methods: Thirty male Sprague-Dawley (SD) rats were randomly divided into a blank group, a model group and a moxibustion group, 10 rats in each group. Except rats in the blank group, the remaining rats were subjected to create long-term exhaustion models by repeated swimming. After successful modeling, rats in the moxibustion group received mild moxibustion at Shenque (CV 8) for 15 min, once every other day with a total of 10 times. Rats in the model group and the blank group did not receive moxibustion. At the end of the treatment, the exhausted times, and the body weight of rats before and after the experiment were compared among groups. The levels of blood malondialdehyde (MDA) and urea nitrogen (BUN), as well as the activities of aspartate transarninase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) were also measured by the automatic biochemical analyzer, 24 h after the exhausting excise. Results: The 10th swimming time was significantly longer in the moxibustion group than that in the model group (P<0.01). The increase rate of the body weight was lower in the rats of the moxibustion group than that in the model group before the 7th and the 10th exhausting excise (P<0.05, P<0.01). The levels of serum MDA and BUN, as well as the activities of AST, ALT and LDH in the model group were higher than those in the blank group (all P<0.01). The levels of serum MDA and BUN, as well as the activities of AST, ALT and LDH in the moxibustion group were lower than those in the model group (P<0.01). Conclusion: Moxibustion at Shenque (CV 8) can decrease the serum levels of MDA and BUN, as well as activities of AST, ALT and LDH in the long-term fatigue rats, thus to improve the symptoms of fatigue.

Objective:To compare the clinical values of minimally invasive Wiltse approach and conventional posterior approach for the treatment of thoracolumbar vertebral fractures.Methods:From November 2010 to June 2014,the pedicle screw-rod fixation system was used to treat thoracolumbar fractures (AO type A)in 50 patients.Among them,28 cases were treated by minimally invasive Wiltse approach,and other 22 cases were treated by conventional posterior median approach. Based on American Spinal Injury Association (ASIA)grading standards,the spinal cord injury function of all cases were grade E before operation.All fractures were single-segment fracture,including T11 in 4 cases,T12 in 10 cases,L1 in 26 cases,and L2 in 10 cases.The time from injury to operation varied from 2 to 13 days (mean,4.9 days).Perioperative parameters,visual analogue scale (VAS)score of postoperative pain and the kyphotic Cobb angle of vertebral bodies for evaluating the correction effect were recorded and analyzed.Results:All cases were followed up for 12-26 months (mean,15 months).The operation time,hospital stay,intraoperative blood loss,and postoperative drainage volume in the group of minimally invasive Wiltse approach were significantly less than those in the group of conventional posterior midline approach (P<0.05 ).The VAS scores in minimally invasive Wiltse approach group were significantly less than those in conventional approach group in 24 and 48 hours after operation (P<0.05).Cobb angles of the two groups were obviously recovered after operation as compared with those before operation (P<0.05),but there were no significant differences between the two groups before and after operation. Conclusions:For the thoracolumbar vertebral fractures (AO type A,ASIA grade E),compared with the conventional approach,minimally invasive Wiltse approach has the advantages of less surgical traumas,less vertebral side tissue injury,easy for pedicle screw insertion,light postoperative lumbar back pain,and effective correction of kyphosis deformity.It is suggested that minimally invasive Wiltse approach is worth to be popularized in remote areas for the treatment of thoracolumbar fractures.

Objective:To compare the safety and efficacy of laparoscopic versus open pancreaticoduodenectomy.Methods:The clinical data of 989 patients who underwent pancreaticoduodenectomy at Hunan People's Hospital from January 2015 to December 2019 were analyzed retrospectively. There were 349 patients in the laparoscopic pancreaticoduodenectomy (LPD) group and 640 patients in the open pancreaticoduodenectomy (OPD) group. Propensity score matching (PSM) was used to match the baseline data of the two groups at a 1: 1 ratio. Data including operation time, intraoperative bleeding, postoperative hospital stay, bile leakage, pancreatic fistula and wound infection were compared between the two groups.Results:After PSM, there were 345 patients in each of the 2 groups. When the LPD group was compared with the OPD group, there were no significant differences in postoperative mortality, reoperation, intraoperative blood transfusion, pancreatic fistula, bile leakage, abdominal hemorrhage, abdominal abscess, severe complications, and pulmonary complication rates. The number of lymph node dissected, R 0 resection and overall survival rates between the two groups were also not significantly different ( P>0.05). However, the operation time of the LPD group (478.2±91.3) min was significantly longer than that of the OPD group (410.8±62.0) min ( P<0.05). On the other hand, the postoperative hospitalization time (10.8±4.3) d, intraoperative bleeding (322.0±362.6) ml, wound infection rate 1.2% (4/345) in the LPD group were significantly better than those in the OPD group [postoperative hospitalization time (12.5±7.9) d, intraoperative bleeding (478.8±570.2) ml, and wound infection rate 5.8% (20/345)] ( P<0.05) . Conclusion:LPD was safe and feasible, and it achieved similar curative effect as OPD.

Objective:To compare between laparoscopic and open pancreaticoduodenectomy in the treatment of distal cholangiocarcinoma.Methods:The clinical data of laparoscopic pancreaticoduodenectomy (LPD group, n=101) and open pancreaticoduodenectomy (OPD group, n=99) in patients with distal cholangiocarcinoma who underwent pancreaticoduodenectomy at Hunan people's Hospital from Jan 2015 to Dec 2019 were analyzed retrospectively. The operation time, intraoperative blood loss, number of lymph node dissection, R 0 resection rate, postoperative hospital stay, postoperative complications and overall survival rate were compared between the two groups. Results:The operation time was (475.0±90.7) min and (444.8±63.3) min, the intraoperative blood loss was (350.9±397.9) ml and (546.7±642.9) ml, the postoperative hospital stay was (11.5±4.7) d and (13.3±5.1) d, the differences were statistically significant ( P<0.05).The number of lymph node dissection was 14.8±3.0 and 15.4±2.4, the R 0 resection rate was 93.1% and 96.0%, respectively, and there was no significant difference ( P>0.05). There was no significant difference in the incidence of residual complications ( P>0.05). During the follow-up of 5-64 months, the OS of 1, 3 and 5 years in the two groups were 90.4%, 41.3%, 20.6% and 94.3%, 50.8% and 24.7%, respectively. ( P>0.05). Conclusions:LPD is safe and feasible in the treatment of distal cholangiocarcinoma, and its short-term curative effect, curative effect and long-term overall survival rate are similar to those of OPD.

OBJECTIVETo investigate the characteristics of collateral circulation in adult moyamoya disease (MMD).

METHODSThe clinical data were collected from all adult patients with MMD undergoing digital subtractive angiography (DSA) in our department from 2006 to 2016. Based on the imaging findings, the patients were divided into ischemia group and bleeding group. A double-blind analysis was conducted of the CT or magnetic resonance imaging findings and the severity of the disease was graded using the modified Suzuki score (mSS). We classified the anastomotic networks in MMD into the superficial meningeal type and deep parenchymal type. The superficial meningeal type was further classified into the leptomeningeal and the durocortical networks, and the deep parenchymal networks into subependymal networks and the inner striatal and inner thalamic networks.

RESULTSNo significant difference was found in the distribution of mSS scores between the hemorrhage group and the ischemic group (Χ=5.812, v=5, P=0.325), but the posterior communicating artery and internal carotid artery diameter ratio (Pcom/ICA ratio) was significantly greater in the hemorrhage group (t=2.119, v=108, P=0.036). The Pcom/ICA ratio differed significantly among the groups with different mSS scores (f=8.924, P=0.00), higher in groups with mSS scores of 3, 4 and 5. The incidence of anterior choroidal artery dilation differed significantly between hemorrhage and ischemic groups (Χ=11.79, P=0.001). The incidences of durocortical networks (Χ=0.327, P=0.567) and subependymal networks (Χ=0.011, P=0.917) were comparable between hemorrhage group and ischemic groups, but the incidence of leptomeningeal networks (P=0.018) and inner striatal and inner thalamic networks (Χ=7.551, P=0.006) differed significantly between the two groups.

CONCLUSIONThe collateral circulation vascular system is an important component of cerebral blood flow in MMD patients and varies from patient to patient. Patients with MMD exhibit increased Pcom/ICA ratio with abnormal expansion of the anterior choroidal artery, and the leptomeningeal networks and the inner striatal and inner thalamic networks are independent risk factors for cerebral hemorrhage.

Ethnomedicine is the precious wealth left by ethnic minorities in their struggle against diseases. It is similar to traditional Chinese medicine in a narrow sense and has the characteristics of multi-component,multi-target and multi-channel synergy. Under the guidance of the theory of ethnomedicine,the combination of ethnomedicine and network pharmacology will help to understand the essence of the prevention and treatment of ethnomedicines in a dynamic and holistic manner. This paper reviews the research progress of network pharmacology applied in ethnomedicine,analyses the problems and challenges existing in the application of network pharmacology in ethnomedicine research at present,such as inaccurate data and information,lack of network analysis platform for effective analysis of dose-effect relationship of chemical constituents and weak basic research of ethnomedicine,and puts forward corresponding prospects.

This study adopted the 4 pairs of simple sequence repeats(SSR) primers selected by National Resource Center for Chinese Meteria Medica (CACMS) to detect 29 populations of Dendrobium officinale samples from 9 main places of production; 5,7,4 and 3 polymorphism bands were amplified from these 4 pairs of SSR primers. The DNA identities of different populations were constructed by SSR. The 29 D. officinale populations could be divided into 4 classes. The clustering result was related to the places of production. Samples from Yunnan,Guizhou,Sichuan provinces were classified into one category,while samples from Anhui and Guangxi provinces were classified into another category. Samples from Guangdong Danxia,Zhejiang Yongkang,Zhejiang Leqing and Taining belonged to a category. PopGene (version 1.32) software was applied to calculate the genetic similarity of the 29 D. officinale populations. The similarities was between 0.403 4 and 1.0.Based on the genetic similarity,the genetic consistency included three classes,A,B and C. Samples with a similar geographical location and landform environment have higher genetic similarities,which indicate the same genetic background. This paper provides reference information to study the identification, selection and breeding of good varieties.
