Due to the instability of intertrochanteric fractures in elderly patients, various methods of reduction and fixation were introduced to obtain stable reduction and solid union, But there have been many controversies regarding advantages between anatomical reduction group and non-anatomical reduction group. The authors analyzed the 68 unstable intertrochanteric fractures out of total 94 cases of intertrochanteric fractures treated from Jan. 1988 to Jan. 1994 with mean follow-up 17 months and evaluated the radiologic and clinical results between those two groups. The results were obtained as follows: 1. The most common cause was low energy injury and according to the Tronzo classification, the type III was most common in 54 cases (79.4%). 2. The average union time was 14.0wks (84%), the union rate was low in the medialized reduction group(A-P) and anterior displaced reduction group(A-P), anterior displaced and anatomical reduction groups(Lateral). 3. The compression length more than 10mm of lag screw was deep in medialized reduction group(A-P), another displaced and anatomical reduction groups(Lateral). 4. The average length of lag screw sliding was 9.2mm and depth sliding of 6.8mm (74%) was occurred within immediate postoperative 1 month.

Os subfibulare is a accessory bone arround the lateral maleolus, but it is different from many other accessory bones in foot and ankle in its development related to trauma and frequent symptoms of ankle instability. Accessory bone is a developmental anomaly which fails to unite to main secondary ossification center and usually asymptomatic. But os subfibulare is developed by recurrent ankle sprains in younger age or non-union of avulsion fracture of anterior talofibular ligament and causes instability of ankle. We experienced two cases of symptomatic os subfibulare in adolecents and report them with review of literatures.

The author performed this study to investige the relationship between condylar movements recorded with Pantronic and mandibular movements at incisal area recorded with BioEGN. For this study 24 patients with Temporomandibular disorders (TMDs) and 30 dental students without any masticatory symptoms were selected as patients group and control group, respectively. The items recorded with Pantronic(Denar Corp., USA) were immediate side-shift, orbiting path, protrusive path, and PRI. BioEGN(Bioelectric-gnathography, Bioresearch Inc., USA) were sued to measure the amount of mandibular torque movement in frontal and horizontal plane and also the distance of mandibular translation at incisal area. Amount of mandibular rotational torque movement was analyzed by angle and difference between both condyles in frontal and horizontal plane. The collected data were processed with SAS program and conclusion were as follows : 1. Mean value of items recorded with Pantronic were not significantly differed between patients group and control group except the item of pantographic reproducibility index(PRI). The value of PRI was 39.5 in patients group, and 29.5 in control group. 2. The amount of mandibular torque movement was not differed tin early protrusive and early left excursion between patients group and control group, but in early right excursion, patients group showed more value than control group did. 3. The distance on sagittal plane in early eccentric movements were longer in patients group than those in control group, but the distance of maximal eccentric movements were not significantly differed between patients group and control group. 4. Items which showed significant correlation with PRI were progressive side-shift, and horizontal torque movement in early protrusion and right excursion. 5. The angle of protrusive path of affected side was greater than of non-affected side in unilaterally affected patients, but the protrusive angle of preferred chewing side was not differed from that of contralateral side in control group. 6. The amount of torque movement in early protrusion and right excursion were greater in patients with coincidence of affected side and preferred chewing side than in patients without coincidence.

A basal cell carcinoma developed in the forehead of a 57-year-old man at the scar site from a blunt trauma that happened 10 months previously. The patient had never been noted to have premalignant or other malignant skin lesions. The significance of injury in the etiology of basal cell carcinoma is discussed.

Objective:To analyze the effect of CD100 to monocyte cytotoxicity in non-small cell lung cancer (NSCLC) patients.Methods:Thirty-five NSCLC patients and thirteen healthy controls were included from Zhengzhou Central Hospital between March 2018 and September 2018. Peripheral blood mononuclear cells (PBMC) and bronchial alveolar lavage fluid (BALF) (both tumor site and non-tumor site) was collected from NSCLC patients, while PBMC was collected from healthy controls. Monocytes were purified from PBMC and BALF. Membrane-bound CD100 (mCD100) and CD72 expression on monocytes was measured by flow cytometry. Monocytes from NSCLC patients were stimulated with recombinant human CD100, anti-CD72, matrix metalloproteinase 14(MMP14), or anti-CD100, and were co-cultured with NCI-H1882 cells for 48 h. Tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), granzyme A, granzyme B level in the supernatants, CD16 expression on monocytes, and percentage of target cell death was assessed. Student t test or paired t test was used for comparison. Results:There were no significant differences of peripheral CD14 + mCD100 + percentage, CD14 + CD72 + percentage, CD100 mean fluorescence intensity (MFI), CD72 MFI between NSCLC patients and healthy controls ( P>0.05). CD14 + mCD100 + percentage, CD14 + CD72 + percentage, CD100 MFI, CD72 MFI was remarkably elevated in tumor site compared with in non-tumor site in NSCLC patients ( P<0.05). There was no remarkable difference of peripheral monocytes-induced NCI-H1882 cell death between NSCLC group and control group [(13.95±3.16)% vs (13.22±2.40)%, P=0.451]. Lung-resident monocytes-induced NCI-H1882 cell death was reduced in tumor site when compared with non-tumor site [(11.61±2.81)% vs (14.19±3.57)%, P=0.008 7]. TNF-α, IL-1β, granzyme A, granzyme B level was also decreased in the supernatants of monocytes from tumor site compared with non-tumor site in NSCLC patients( P<0.05). However, there was no statistical difference of CD16 level between two groups( P=0.666). Recombinant human CD100 stimulation promoted NCI-H1882 cell death induced by monocytes from tumor site when compared with unstimulated cells ( P<0.000 1). TNF-α, IL-1β, granzyme A, granzyme B level was also increased ( P<0.05). However, Monocytes, which were pretreated with anti-CD72, induced decreased NCI-H1882 cell death and TNF-α, IL-1β, granzyme A, granzyme B secretion in response to recombinant human CD100 stimulation ( P<0.05). Recombinant human MMP14 stimulation decreased CD14 + mCD100 + percentage and increased soluble CD100 (sCD100) level. NCI-H1882 cell death and TNF-α, IL-1β, granzyme A, granzyme B level was elevated when compared with unstimulated cells ( P<0.05). Anti-CD100 administration decreased sCD100 level. NCI-H1882 cell death and TNF-α, IL-1β, granzyme A, granzyme B level was elevated when compared with MMP14 stimulated cells ( P<0.05). Conclusions:CD100 shedding was insufficient in tumor infiltrating monocytes in NSCLC patients, leading to decreased cytotoxicity. MMP14 might elevate cytotoxicity of tumor infiltrating monocytes via promoting CD100 shedding and sCD100 formation.

42 knees with degenerative arthritis underwent arthroscopic lavage and 7 knees underwent arthroscopic lavage combined with multiple bone drilling in between 1994 and 1995 and followed average 12 months. Clinical evaluation using the hospita1 for specia] surgery knee scores (HSS scores) was done at last follow up and classified into 4 groups: excellent (90-99), good (80-89), fair (70-79) and poor (less than 70). The results were as follows: l. Of the 42 knees of the lavage group, 6 knees (16%) was excellent, 14 knees (33%) good, ]7 knees (40%) fair and 5 (11%) knees poor. Success group (Excellent & Good) were achived in 20 knees (49%). 2. Of 17 knees treated with arthroscopic lavage comhined with multiple bone drillig resulted in excellent in 9 knees (53%), good in 4 knees (23%), fair in 2 knees (12%) and poor in 2 knees (12%). Success group were achived in 13 knees (76%). 1n conclusion, we helieve that multiple bone drilling in conjunction with arthroscopic lavage has more favorable effect on the pain relief for degenerative osteoarthritis of the knee than arthroscopic lavage only.

BACKGROUND: Cardiogenic shock is the most common cause of in-hospital mortality after acute myocardial infarction. Despite improvement in coronary care, the in-hospital mortality rate of cardiogenic shock is very high in conventional conservative therapy. Recently, it was suggested that coronary angioplasty may reduce the mortality associated with cardiogenic shock. METHOD: Thirteen consecutive patients with cardiogenic shock who underwent coronary angioplasty were studied. Shock was not induced by mechanical complications, arrhythmia, hypovolemia and other reversible cause. We collected and analyzed the clinical, hemodynamic survivor groups. RESULTS: Of 13 patients, 11 had successful reperfusion of the infarct-related coronary artery and 2 had unsuccessful reperfusion. Of 11 patients with successful angioplasty, 8 survived at the time of hospital discharge. All patents with unsuccessful angioplasty died in the hospital. Therefore overall hospital survival rate was 62% and the rate increased to 73% in patients with successful reperfusion. Survivor and non-survivor groups in clinical, hemodynamic and angiographic variables were similar except systolic blood pressure and the presence of successful reperfusion. CONCLUSION: In patients with cardiogenic shock, the patency of infarct-related coronary artery was strongly associated with in-hospital mortality. This findings support aggressive interventional strategy in patient with cardiogenic shock complicating acute myocardial infarction.
