OBJECTIVE: To explore the role of the innate immune factors TLR2 and TLR4 in the pathogenesis of chronic rhinosinusitis (CRS) by detecting their expression in different clinical types of CRS and the normal control group. METHOD: Immunohistochemistry was used to detect the expression of TLR2 and TLR4 respectively in 21 cases (chronic rhinosinusitis with nasal polyps, CRSwNP) group, 15 cases (chronic rhinosinusitis without nasal polyos, CRSsNP) group, 11 cases recurrent CRSwNP group and 13 cases control group. Positive cells were counted under the microscope artificially, Mann-Whitney U analysis was applied for the ranked data, and one-way anova analysis was adopted to analyze the experimental group and control group. RESULT: (1) TLR2 and TLR4 expression had the same characteristics. Expression mainly concentrated in parts of the whole layer of epithelial basement membrane, cytoplasm of glandular cells, very few inflammatory cells such as monocytes and plasma cells in the cytoplasm, sometimes unknown cell nuclei positive expression. (2) The glandular cells were stained manual counting and color grading. TLR2 and TLR4 packet application Wilcoxon rank test Mann-Whitney U test analysis was not statistically significant (P > 0.05), measurement data within the group variance statistical difference between the groups (P < 0.05). CONCLUSION The Nasal mucosa can produce the innate immune factors TLR2 and TLR4. The different expression of TLR2 and TLR4 in the various clinical types of CRS suggests that they play the certain role in the pathogenesis of CRS.

OBJECTIVETo investigate the relationship between degree of abnormal deeper lateral femoral notch between anterior cruciate ligament tear.

METHODSThe radiograph and MRI image material of 16 patients with anterior cruciate ligament injury from January 2013 to November 2013 were reviewed including 14 males and 2 females with an average age of 28.3 years old ranging from 18 to 52 years. Eleven cases was on right side and 5 on left. Survey tool of PASC imaging system was used to measure the depth of lateral femoral notch in patients with abnormal indicated by lateral X-ray view or sagittal view of MRI in knee joint,while clinical data,physical examination,image material in arthroscopy of these patients were retrospective researched.

RESULTSFour patients had an abnormal lateral femoral notch with the depth of 2 mm on lateral X-ray and sagittal MRI, while positive anterior drawer sign and Lachman test as well as anterior cruciate ligament tears on MRI, and completed tears were comfirmed on the operation of arthroscopy. Two patients without abnomal lateral femoral notch on lateral view of X-ray while with the depth of 1 mm on sagittal view of MRI were also coupled with positive anterior drawer sign and Lachman test as well as anterior cruciate ligament tears on MRI, and one of them were comfirmed completed anterior cruciate ligament tears on the arthroscopy operation and completed tear could not comfirmed on another one because of disagreed with arthroscopy operation.

CONCLUSIONThere appears to be an association between abnormal lateral femoral notch on lateral view of knee with anterior cruciate ligament tears. An abnormal deeper lateral femoral notch is an indirect evidence for anterior cruciate ligament tears.

OBJECTIVETo compare the difference in clinical efficacy on polycystic ovary syndrome (PCOS) between electroacupuncture (EA) and dyne-35 and to explore the effect mechanism.

METHODSSixty-five patients were randomized into an EA group (33 cases) and a western medication group (32 cases). In the EA group, the selected acupoints were Danzhong (CV 17), Qimen (LR 14), Zhongwan (CV 12), Tianshu (ST 25), Guanyuan (CV 4), Zigong (EX-CA 1), Sanyinjiao (SP 6), Zusanli (ST 36) and Taichong (LR 3), etc. After the arrival of qi, electric stimulation was attached to the acupoints for 30 min. The treatment was given 3 times a week. In the western medication group, dyne-35 was prescribed on the 5th day of natural menstruation or withdrawal bleeding, one tablet a day, continuously for 21 days. The treatment cycle was 3 months in the two groups. The menstrual condition, body mass, body mass index (BMI), serum testosterone (T), luteinizing hormone (LH), follicle-stimulating hormone (FSH) and LH/FSH were compared before and after treatment in the two groups. The clinical efficacy was assessed in the two groups.

RESULTSThe total effective rate was 90.6% (29/32) in the EA group and was 93.3% (28/30) in the western medication group. The efficacy was similar in the two groups (P > 0.05). After treatment, the levels of LH and LH/FSH were all reduced significantly in the two groups (all P < 0.01). After treatment, T level in serum was reduced apparently in the western medication group (P < 0.05). Before and after treatment, the differences in body mass and BMI in the EA group were more significant than those in the western medication group (P < 0.01, P < 0.05).

CONCLUSIONEA is the effective method for PCOS, similar to that of dyne-35. The effect of it for weight loss is superior to dyne-35 and no apparent adverse reactions happen. The effect mechanism of EA is related to the regulation of serum sexual hormone levels and their ratio, as well as to the regulation of body lipid metabolism.
