Objective To analyze the data collected from surveillance sites in Shanxi province in epidemiological investigations during 2004 - 2008 and understand the influence of such factors as rat density and vectorial quantities on plague epidemic intensity, thus provide some scientific basis for plague control and prevention. Methods To collect the data of surveillance during 2004 - 2008 in the 12 counties of plague surveillance by retrospective method. Sort and analyze the collected data according to the requirement of operational scheme for plague surveillance-calculate the rat density of spermophilus dauricus, meriones meridianus and the small rodents, and the flea index and the flea infection ratio of body flea, burrow track, cave. The results of serological tests were analyzed at the same time. Results As showed in the results, the mean density of spermophilus dauricus was 1.12 merely in each hectare, and that of meriones meridianus and small rodents were 7.42%(2130/28 700) and 8.03%(3886/48 400), respectively. The flea infection rate of spermophilus dauricus and meriones meridianas were 25.78% ( 1933/7497 ) and 44.19% (2028/4598), respectively;the flea index of spermophilus dauricus and meriones meridianus were 0.59 and 1.84, respectively. The number of nests excavated with flea for spermophilus dauricus was 70, and the numbers of nests and flea were 362 and 333, respectively. The flea infection rate was 19.34 % (70/362), and the flea index was 0.92. The number of nests excavated with flea for meriones meridianus was 34, and the numbers of nests and flea were 177 and 124, respectively. The flea infection rate was 19.21%(34/177), and the flea index was 0.70. The number of caves explored for spermophilus dauricus was 7171,and the number of burrows with flea was 62, so the flea infection rate was 0.86%(62/7171 ), and the flea index was 0.01. Conclusions With a relatively high density and large quantity and considering the epidemic features of animal plague in periphery provinces in recent years, plague may still happen and spread in Shanxi province diespite the negative results of all those serological tests, by means of importing from other provinces.

Objective:To explore the clinical characteristics of patients with pituitary thyrotropin-secreting adenoma and evaluate the effect of preoperative short-acting octreotide treatment on hyperthyroidism.Methods:A retrospective analysis was performed in 40 patients with pituitary thyrotropin adenoma diagnosed in Beijing Tiantan Hospital from January 2008 to January 2018. The general data, laboratory examinations and imaging findings were reviewed and analyzed. The clinical effect of preoperative octreotide on hyperthyroidism was evaluated.Results:The age of onset year of the 40 patients (male: female = 24∶16) was (30.5±5.1) years. Among them, 35 patients (87.5%) were with macroadenoma. The most common symptoms were thyroid hypermetabolism syndrome, followed by headache, dizziness, visual field damage and hypogonadism. The thyroid function of 30 patients (75%) recovered to normal within 3-5 days after the octreotide treatment. The total effective rate of the octreotide was 90.0%. The level of free thyroxine (FT 4) before treatment in patients with more than 10 times of effective cumulative dose was significantly higher than that in patients with less than 10 doses. Conclusions:Thyroid hypermetabolism syndrome and pituitary occupying effect are the most common clinical manifestations of thyrotropin-secreting adenoma. Preoperative octreotide treatment can effectively control hyperthyroidism. The level of FT 4 is a crucial factor affecting the efficacy of octreotide.

OBJECTIVETo study on the reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in total knee arthroplasty (TKA) the rotational alignment reference bony landmarks of the proximal tibial component on magnetic resonance image (MRI) were measured.
METHODSFrom January 2010 to December 2013, 80 normal knees of Chinese volunteers including 35 males and 45 females with an average age of (35.4±6.1) years were reviewed. The images of the knees were obtained by MRI. The surgical epicondylar axis (STEA) was identified in the femoral transverse sections and then was projected to the side of tibia, forming the SETA'. A line connecting the medial border of the patellar tendon and the middle of the posterior cruciate ligament insertion (Akagi line) and its vertical line (AK), as well as a line connecting the medial 1/3 of the patellar tendon and the middle of the posterior cruciate ligament insertion and its vertical line (AP), were identified in the tibial transverse sections. The angles were measured between the AK, AP and STEA'.
RESULTSThe angle between AK and STEA' was (0.59±2.07)°, and there was no significant difference between the two lines (t=-2.54, P=0.13). The mean angle between AP and STEA' was (3.21±2.04)°, and there was a significant difference between the two lines (t=14.05, P<0.05). There was a significant difference between the AK and AP (t=-11.68, P<0.05).
CONCLUSIONThe reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in TKA is good.

Objective To evaluate the clinical significance of quantitative sensory testing (QST) in screening diabetic peripheral neuropathy of the early stage. Methods One hundred patients with type 2 diabetes mellitus were examined by nerve conduction velocity (NCV) and QST examination. With the NCV positive as the gold criterion for screening diabetic peripheral neuropathy of the early stage, the sensitivity and specificity of QST was further analyzed for diagnosis of the early stage diabetic peripheral neuropathy. Results Among the 100 patients with type 2 diabetes mellitus,there were 41 cases positive and 59 cases negative in NCV examination. On the other hand,there were 74 cases positive,and 26 cases negative in QST. The sensitivity and specificity of QST for the diagnosis of early stage diabetic peripheral neuropathy was 97.56% (40/41) and 42.37% (25/59). Conclusions In the screening of early stage diabetic peripheral neuropathy,QST shows higher detection sensitivity,but lower specificity than NCV examination. Therefore, QST may be an examination for the supplement of the routine electromyography.

Objective To studythe cephalocaudal relationship ofabdominal aortic bifurcation relative toumbilicus and iliac crest vertex and their correlations with abdominal adipose tissue thickness and age. Methods The vertical distances,cephalocaudal relationship and other related anatomic parameters of aortic bifurcation relative to umbilicus and iliac crest vertex in 108 patientswere measured by consecutive abdominal CT scanning. The correlations of the acquired data with abdominal adipose tissue thickness and age were analyzed using Pearson correlation coefficient. Results Umbilicus was located at cephalad to aortic bifurcation in 67 patients(62.0%), caudal in 34(31.4%)andthe same level in 7(6.5%),with the vertical distance of(4.53 ± 17.51)mm to the aortic bifurcation. No statistically significant relationship was found between abdominal adipose tissue thickness(P>0.05) or age(P>0.05). Iliac crest vertex relative to aortic bifurcationwas located at cephalad,caudal and the same level in 31,71 and 6 patients,taking up 28.7%,65.7%and 5.6%,respectively. Its vertical distance to the bifurcation was(-6.34 ± 14.49)mm,nonrelated with abdominal adipose tissue thickness(P>0.05),but positively correlated with age(P<0.01). The difference in the cephalocaudal relationship of aortic bifurcation relative to umbilicus and iliac crest vertex was statistically significant(P<0.01). Conclusion Compared with iliac crest vertex,umbilicus is an important landmark of locating abdominal aortic terminal occlusion position in vitro because it mostly lies cephalad to aortic bifurcation in the front of the body,not easy to vary with abdominal adipose tissue thickness and age.
