OBJECTIVE:
To provide reference of the ideal entry point for antegrade femoral nailing according to analysis correlation between highest point of greater trochanter and the middle line of the medullary cavity in adults by three-dimensional images.
METHODS:
From January 2016 to January 2017, 107 adults who underwent continuous computed tomography (CT) scans were ultimately enrolled, including 64 males and 43 females with an average age of (51.7±16.4) years old;54 patients on the left side and 53 patients on the right side. Three-dimensional images were built by using image-processing software (Volume Viewer) to reconstruct geometry of cortex and medullary canal. All people weregrouped according to different femoral greater trochanter morphology, such as anterior apex (AA), posterior apex (PA), middle apex (MA) and none apex (NA). Forwards inclination was adjusted to apparent neck shaft angle (ANSA) and true neck shaft angle (TNSA) on the coronal and saggittal view, recorded as C-ANSA, C-TNSA, S-ANSA, S-TNSA respectively, vertical distance from the middle line of femur medullary cavity to the highest point of greater trochanter of femur on the 4 positions were measured and performed statistical analysis, multiple linear regression was applied to analysis relationship between clinical data and VD value.
RESULTS:
(1)Comparison of VD value among 4 groups on the 4 positions, there were no difference in VD value between AA and MA groups on the S-ANSA position;and no differences in VD value among AA, MA and NA groups on the C-ANSA and C-TNSA position. (2)There were differences in VD value among AA, MA and NA groups on the sagittal plane;while had difference in VD value between PA and NA group on the coronal plane. (3)Prediction equation of VD value on S-ANSA and S-TNSA position by multiple linear regression showed R=0.343, F=3.409, =0.012 on the S-ANSA position;R=0.317, F=2.846, =0.028 on the S-TNSA position; neck shaft angle and sex were risk factors of VD value on the sagittal plane, while no difference in VD value on the coronal position.
CONCLUSION
(1)When indentify insertion point in adult femoral nail according to the highest point of greater trochanter as anatomic landmark, the morphology of greater trochanter of femur should be distinguished to certain observation position, then evaluate migration before and after on the sagttial plane and lateral offset on the coronal plane. (2)Migration before and after on the sagttial plane is increase with increase of neck shaft angle, and the degree of migration of female before and after is less than that of male.

OBJECTIVETo make a study of the effect of Chaihu Shihuang soup on blood serum level TNF, IL-6 and IL-10 of severe acute pancratitis.
METHODSixty SAP cases were divided at random into treatment group and control group (30 cases each). The treatment group were given chai-hu-shi-huang-soup once a day; the control group were given Dachaihu soup once daily, with both treatment period for 7 days. The tumor necrosis factor-alpha (TNF-alpha), interleukin level 6 (IL-6) and 10 (IL-10) of both groups were determined before and after the treatment. We also had 30 healthy cases.
RESULTIL-10 level in both groups was lower than healthy group while TNF-alpha and IL-6 were higher than healthy group (P < 0.01). After treatment, the treatment group's TNF-alpha, IL-6 level were comparatively lower than that in the control group (P < 0.01), and IL-10 level were clearly higher than that of the control group (P < 0.01), comparison of the treatment group before treatment (P < 0.01).
CONCLUSIONChaihu Shihuang soup can significantly regulate cytokine and improve early recovery of SAP.

Objective To analysis of risk factors for left atrial thrombosis in patients with rheumatic mitral stenosis.Methods From January 2001 to December 2008, 2277 patients with rheumatic mitral stenosis underwent operations in our hospital. There were 737 males and 1540 female, the age ranged from 19 to 84 years [average (50.9 ±10.2) years]. Left atrial thrombosis group (554 cases) and no thrombosis group (1723 cases) were divided, retrospectively collected data were analyzed with univariate and multivariate Logistic regression. Results 12 bvariables, including age, mitral valve orifice area, left atrial diameter, left ventricular diastole diameter, CRP, gender , degree of mitral stenosis, or regurgitation, degree of bicuspid regurgitation, degree of pulmonary hypertension, atrial fibrillation and heart function had statistic difference between two groups. With multivariate Logistic regression for these 12 factors, age, mitral valve orifice area, left atrial diameter, degree of mitral regurgitation and atrial fibrillation were found to be the affecting factors for left atrial thrombosis in patients with rheumatic mitral stenosis. Conclusion For patients with rheumatic mitral stenosis, age, mitral valve orifice area, left atrial diameter and atrial fibrillation are the risk factors for left atrial thrombosis. Mitral regurgitation is a protective factor for left atrial thrombosis.

Background: It is unknown if medication-overuse headache, clinically similar to chronic tension-type
headache, has pre-attentive problems which may be related to pain or substance abuse. Methods:
Auditory frequency deviance elicited mismatch negativity was recorded from 22 patients with chronic
tension-type headache, 26 with medication-overuse headache from underlying chronic tension-type
headache and 41 healthy volunteers as controls. Their depression and anxiety scores were noted.
Results: There were no signifi cant differences in the N1 latency or amplitude to both standard and
deviant stimuli for the different groups. However, the latency and amplitude of mismatch negativity were
signifi cantly shortened and reduced at Fz, Cz, and Pz in medication-overuse headache as compared to
chronic tension-type headache and normal subjects. Anxiety levels were elevated in chronic tensiontype
headache and medication-overuse headache subjects compared to healthy controls but were not
correlated with mismatch negativity latency or amplitude in a given group.
Conclusions: In medication-overuse headache subjects, the shortened mismatch negativity latency
indicates quick involuntary attention switching to auditory change, while its reduced amplitude
indicates poor accuracy in discriminating early stimuli, which may be related to medication overuse
rather than to the head pain experienced.

OBJECTIVETo make a study of the influence of the intervene of traditional Chinese medicine on cytokine level in benign prostatic hyperplasia.
METHODThe patients were divided into treatment group (group A), control group (group B) and healthy group (group C) with the randomly compared researching method. Group A were given Qianliening Tang (QLNT), daily potion, two times a day. Group B were given Qianliekang, three times a day, three pills each time. The course of both treatment lasted for 8 weeks.
RESULTBefore treatment, TNF-alpha, IL-17/IL-10, IL-4 in group A and B are obviously out of order compared with group C (P < 0.01). After the treatment, TNF-alpha, IL-17 in group A decreased dramatically and IL-10, IL-4 increased, which shows great differences compared with those before treatment and with group B (P < 0.01), but still can't reach to group C level.
CONCLUSIONQian liening Tang can efficiently regulate the level of suppressive inflammatory cytokines and proinflammatory cytokines. It provides scientific experimental basis for clinical diagnosis and treatment of the disease.
