The early histological myocardial ischemic changes in both experimental rabbitsand forensic caseworks of sudden death were demonstrated by the hematoxylin basicfuchsin-picric acid staining method.After the ligation of the coronary artery,therewere discrete patchy fuchsin-stained fibers which in contrast with the normal fibersof light-brown color.The number of fuchsin-stained fibers increased with the pro-longation of the intervals after ischemia.The results were not affected by the post-mortem autolysis.We consider that this method can be used as a routine test ofearly myocardial ischemia in both clinico-pathology and forensic pathology.

Objective To identify and analyze the species of vaginal lactobacilli between patients with bacterial vaginosis (BV) and healthy women at childbearing age in Inner Mongolia. Methods From Jun. 2008 to Dec. 2008, 203 Mongolian healthy women, 74 Han healthy women and 102 Mongolian patients with BV from 3 pastoral areas were enrolled in this study. Isolation and culture of lactobacilli from vaginal wall were performed by modified culture medium. DNA of lactobacilli were extracted and sequenced. H2O2 were detected by TMB-HRP-MRS. Results(1)The rate of lactobacilli identification were 76.8%(156/203) in Mongolian healthy women and 21.6% (22/102) in Mongolian patients with BV, which reached statistical difference(P＜0.01).Lactobacilli identification in Han healthy women [82.4%(61/74)] did not show significant difference with that of Mongolian healthy women (P＞0.05). (2) The total of 193 strains and 11 species of Lactobacillus were detected in 203 Mongolian healthy women. Meanwhile,22 strains and 4 species of Lactobacillus were found in 102 Mongolian BV cases.(3)The rate of H2O2 generating Lactobacilli was 27.3% (6/22) in Mongolian BV patients and 75.7% (56/74)in Mongolian healthy women, which showed statistical difference(P＜0.05). Conclusions The rate of Lactobacillus was not related with the race of women in pastoral area in Inner Mongolian. The amount of lactobacilli and H2O2 generating Lactobacilli in the vagina of BV patients was remarkably lower than those of healthy women at childbearing age.

OBJECTIVETo compare therapeutic effects of clavicular hook-plate fixation and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation in treating Tossy type III acromioclavicular joint dislocation.

METHODSForty-one patients with Tossy type III acromioclavicular dislocation treated by operation were retrospectively analysis from January 2012 to January 2014. The patients were divided into clavicular hook-plate fixation group (group A) and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation (group B) according to surgical procedures. In group A, there were 15 males and 6 females aged from 17 to 51 years old with an average of (31.60 ± 12.58) years old, preoperative Constant-Murley score was 40.25 ± 9.80, and treated with clavicular hook-plate fixation. In group B, there were 13 males and 7 females aged from 18 to 48 years old with an average of (29.40 ± 11.27) years old, preoperative Constant-Murley score was 41.45 ± 8.81, and treated with modified Weaver-Dunn surgery combined with clavicular hook-plate fixation. Operative time, blood loss, imaging changes before and after operation, postoperative complications were compared; Constant-Murley score at 3, 6 and 12 months after operation were evaluated.

RESULTSIn group A, operative time was 40.50 ± 24.36) min, blood loss was (75.30 ± 30.36) ml; In group B, operative time was (60.10 ± 23.55) min, blood loss was (100.70 ± 40.12) ml. Twenty-one patients in group A were followed-up from 12 to 18 months with an average of (14.8 ± 3.1) months; 20 patients in group B were followed-up from 12 to 14 months with an average of (13.6 ± 1.5) months. There were no significant differences in operative time, blood loss and follow-up time between two groups. Complications were in six patients of group A and 3 patients of group B, and there were no significant meaning between two groups. At 6 months after operation, Constant-Murley score in group A was 88.85 ± 4.23, 92.15 ± 3.82 in group B; and had significant meaning between two groups (t = -2.56, P = 0.022 < 0.05). While there were no differences in Constant-Murley score in other times.

CONCLUSIONBoth of clavicular hook-plate fixation and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation are effective operative methods for the treatment of Tossy type III acromioclavicular dislocation. Clavicular hook-plate fixation has advantage of less trauma, while modified Weaver-Dunn surgery combined with clavicular hook-plate fixation could reconstruct coracoclavicular ligament more stronger, clavicular hook plate could take out earlier, also improve shoulder joint function earlier.

AIM:To investigate the application of retinal nerve fiber layer (RNFL) thickness detected by OCT in the diagnosis of primary open angle glaucoma (POAG) and its relationship with the mean defect of visual field.METHODS:A retrospective study was carried out.Totally 158 cases (158 eyes) of patients with POAG were selected as POAG group, including 81 cases in early stage, 47 cases in middle stage and 30 cases in late stage.At the same time, 50 cases of persons without eye related diseases were selected as the control group.The upper, lower, nasal and bitamporal RNFL thickness and mean defect of visual field were detected, and the patients with POAG were followed up for 3mo.RESULTS:The upper, lower, nasal and bitamporal RNFL in POAG group were thinner than those in the control, and the mean defect of visual field was higher than that in the control group at different time (P<0.05).There was no significant difference in RNFL thickness and mean defect of visual field between patients with early POAG and the control group (P>0.05).The RNFL thickness of various parts was higher than that in patients with middle and late POAG, and the mean defect of visual field was lower than that in patients with middle and late POAG (P<0.05).There was no significant difference in RNFL thickness of various parts and mean defect of visual field in POAG group at different time (P>0.05).Pearson correlation analysis showed that the upper, lower, nasal and bitamporal RNFL thickness was negatively correlated with the mean defect of visual field (r=-0.719,-0.615,-0.681,-0.518, P<0.05).CONCLUSION:OCT can monitor the change of RNFL thickness in patients with POAG, and has a negative correlation with mean defect of visual field, which can be used for early diagnosis of POAG.

To analyze the causes and treatments of high intraocular pressure ( > 21mmHg ) of angle - closure glaucoma underwent compound trabeculectomy 1mo after surgery.
●METHODS: This was a retrospective study of our hospital, from March 2010 to March 2013. Thirty-four (38 eyes) of angle-closure glaucoma patients were collected, who underwent compound trabeculectomy with high intraocular pressure ( > 21mmHg) 1mo after operation. We analyzed the causes and summarized the treatments.
●RESULTS:The causes which lead to early postoperative high intraocular pressure included malignant glaucoma (9 eyes of 8 cases), blood clot and connective tissue block under the scleral flap (15 eyes of 13 cases), hyphema after surgery(5 eyes of 5 cases), sclera flap incision was incarcerated with iris tissue ( 3 eyes of 3 cases ), preoperative high intraocular pressure for a long time(5 eyes of 4 cases), 1 eye of 1 case for unknown reason. After proper treatments, intraocular pressures of all patients were bellowed 21mmHg.
● CONCLUSlON: Early postoperative high intraocular pressure of angle - closure glaucoma underwent compound trabeculectomy is caused by various factors, and the early prevention and timely treatment are key points of a successful operation.

OBJECTIVE To investigate enhanced immune function of methionine encephalin (MENK) and its anti-tumor mechanism in CT26 colon cancer mouse model. METHODS 3×106 CT26 cells were implanted subcutaneously in BALB/c mice. Four days after, MENK was peritoneally administrated at the concentration of 20 mg·kg-1 for 14 d. The percentage of MDSCs in bone marrow, spleen, blood, tumor and liver were detected by flow cytometry. Non- esterified fatty acid (NEFA), triglycerides (TG) and total cholesterol (T-CHO) in liver homogenate were tested by a NEFA test kit, a TG test kit and a T- CHO test kit respectively. qRT- PCR and Western blot were used to measure mRNA and protein levels of inflammation-, glycometabolsim- and lipometabolsim-associated indexes in liver. RESULTS MENK decreased percentages of MDSCs in bone marrow, spleen, blood and tumor in colon cancer mice. MENK-treated mice displayed elevated ratio of CD4+T and CD8+T cells in spleen as well as increased T and B lymphocytes proliferation. Meanwhile, MENK also ameliorated liver damage reflected by lower levels of GPT and GOT in serum and reduced risks of cancer- associated index including inflammation, high lipid and high glucose. Furthermore, MENK lowered down the levels of NEFA, TG and T- CHO in liver homogenate. MENK treatment decreased expression of p- STAT3, increased expression of p-AKT, IRS1 and Glut4 at protein level as well as reduced lipogenesis-associated genes and elevated glycolysis-associated genes in liver of tumor bearing mice. Also, abated expression of genes associated with MDSCs generation (M-CSF, GM-CSF, IL-6, IL-1β) and migration (S100A9, KC) was observed within shrunken subcutaneous tumor by MENK intervention. CONCLUSION MENK has the ability to strength immune function against colon cancer by reducing MDSCs and improving liver metabolism.
