?Optic neuritis ( ON) is one of the most common causes of vision loss by neural eye diseases in youth and middle-aged. In the past, the diagnosis simply according to the risk position, which did not distinguish from the pathogenesis and clinical characteristics, can not meet the current clinical diagnosis and treatment needs. Combining with the etiology, clinical characteristics and prognosis, the latest classification of the current international diagnosis of ON are typical and atypical ON. Typical ON relates to multiple sclerosis ( MS ) or demyelinating disease of the central nervous system, it has a relatively good therapeutic effect and prognosis. Rather than, atypical ON has complex etiology, clinical manifestation, and the treatment and prognosis are also different. At present there are many international ON treatment guidelines with level I evidence-based medical evidence, but with different genetic background, geographical environment and ethnic groups, they are not been determined. China lacks of such a multicenter large sample, a wide range of research evidence. In this paper, we will summarize the progress of the diagnosis and treatment about ON, especially about the atypical ON, in order to provide some suggestions to further improve the standardization and individualization for clinical diagnosis and treatment on ON.

OBJECTIVETo investigate the effects of total flavonoids of propolis (TFP) on apoptosis of myocardial cells of chronic heart failure and its possible mechanism in rats.

METHODSSix male SD rats were randomly selected as normal control group, the remaining rats were made as chronic heart failure (CHF) model by intraperitoneal injection of adriamycin. The rats in the successful model were randomly divided into five groups (n = 6): CHF group, total flavonoids of propolis low dose group (LD group), total flavonoids of propolis middle dose group (MD group), total flavonoids of propolis high dose group (HD group), digoxin group (DIG group). After six week treatment, cardiac function indexes of rats were recorded by signal acquisition system; brain natriuretic peptide (BNP), cardiac troponin I (cTnI), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) content in plasma were detected; Myocardial morphological changes and collagen fiber hyperplasia by HE and Masson staining were observed; Myocardial apoptosis was detected with TUNEL method and protein connexin 43(P-Cx43) expression was detected by Western blot method.

RESULTSCompared with NC group, left ventricular systolic pressure(LVSP) and maximal rise/fall velocity of left ventriculad pressure (± dP/dt(max)) absolute value in CHF group were significantly lowered (P < 0.01) while left ventricular end diastolic pressure (LVEDP) was increased significantly (P < 0.01); Contents of plasma BNP, cTnI, TNF-α and IL-6 in the CHF group were significantly improved (P < 0.01). Compared with CHF group, LVSP, ± dP/dt(max) absolute value in MD and HD groups were increased (P < 0.05), and LVEDP was significantly lowered (P < 0.01); LVEDP in LD group was significantly lowered (P < 0.01), changes in LVSP and ± dp/dt(max) absolue value were not obvious (P > 0.05). BNP, cTnI, TNF-α and IL-6 contents in MD and HD groups were significantly reduced (P < 0.01), but those plasma indicator changes were not obvious in LD group (P > 0.05). Western blot showed that P-Cx43 expression in CHF group was significantly higher than that in NC group (P < 0.01) and that in all TFP treatment groups it was decreased compared with CHF group (P < 0.05, P < 0.01), among which pairwise comparisons also showed differences (P < 0.05), myocardial apoptosis index (%)(22.62 ± 3.39) in CHF group was higher than that in NC group( 1.12 ± 0.24) (P < 0.01); compared with CHF group, the apoptosis index of myocardial cells (%) in LD,MD and HD groups, (15.79 + 2.8), (9.28 + 2.1) and (4.73 + 1.14) respectively, were significantly lower than those in the CHF group( P < 0.01). The expression level of P-Cx43 positively correlated with the apoptotic index (r = 0. 861, P < 0.01).

CONCLUSIONTotal flavonaids of propolis have inhibitory effect on apoptosis of myocardial cells of chronic heart failure induced by adriamycin in rats, and the mechanism may be closely related to the regulation of Cx43 expression, especially the regulatory phosphorylation status.

Objective To observe the expression of P21 and CDK6 in cervical squamous cell carcinoma,and to investigate the relationship between their expression and cervical squamous cell carcinoma.Methods The expression of CDK6 and P21 in 100 cases of cervical squamous cell carcinoma,20 cases of cervical CIN lesions and 20 cases of normal cervical tissues were detected by immunohistochemical ABC method,and the relationship between them and tumor differentiation,invasion depth,lymph node metastasis and clinical stage were analyzed.Results The expression rates of P21 and CDK6 in cervical squamous cell carcinoma tissues were significantly higher than those in CIN lesions and normal cervical tissues;The low expression of P21 was associated with the depth of tumor invasion,lymph node metastasis and clinical stage (P＜0.05),and was not associated with the degree of tumor differentiation (P＞0.05);The high expression of CDK6 was associated with tumor differentiation,invasion depth,lymph node metastasis and clinical stage (P＜0.05).Conclusion The abnormal expression of P21 and CDK6 may play an important role in the occurrence and development of cervical squamous cell carcinoma,and the two may have a certain significance in the prognosis of cervical squamous cell carcinoma.

Objective: To evaluate the antipyretic action of Xiaoerreganning Oral Solution on acute upper respiratory tract infection of children. Methods: 161 children with acute upper respiratory tract infection were randomly divided into 3 groups. 60 patients at different age ranges in Xiaoerreganning Oral Solution group were treated with Xiaoerreganning Oral Solution at different dosags, 3～4 times every day. The treatment course was 3 days. Patients' body-temperatures before and after treatment were recorded. The temperature differences in various time points before and after treatment were computed, and compared with the results of Shuanghuanglian Oral Solution group and Wei C Yingqiao Tablets group.Results: All three drugs could reduce the patients' body-temperatures gradually, but the antipyretic action of Xiaoerreganning Oral Solution was the strongest. There were significant differences in temperature difference between Xiaoerreganning Oral Solution Group and Wei C Yinqiao Granules (in 2 or 6h after treatment and in 1 day or 3 days after treatment, P

OBJECTIVETo study the relationship between gene p53 codon 72 polymorphism and pathological scar formation occurrence after caesarean section.

METHODSThe method of molecular beacon with real-time PCR was applied to detect gene polymorphism of p53 codon 72 in blood samples taken from 303 pregnant women (within a week after caesarea section). The clinical visits were taken 3 times for 12th to 18th months to ascertain clinical formation of pathological scar and its relationship to genotype of p53. The chi-square method was used to analyze the relationship of p53 gene polymorphism and abnormal scar formation occurrence by statistical software SPSS 13.0.

RESULTSTotal of 303 pregnant women were assayed. 30 patients were found with pathological scar by clinical visit in the total 303 pregnant women. The genotype frequencies of total three types (C/C, C/G and G/G) of p53 gene codon 72 in patients with pathological scar are significantly different from that of normal pregnant woman. The frequency of C/C genotype in patients are higher than that of normal pregnant women (P < 0.01). The frequency of C/C genotype in these patients with pathological scar is higher (46.7%, 14/30) than C/G (33.0%, 10/30, P < 0.01) or G/G (20%, 6/30) genotype (P < 0.01). The C allele frequency in the patients is 63.7%. It is also higher than G allele (36.7%, P < 0.01). The OR value is 2.30. Therefore the C allele of p53 gene codon 72 is a risk factor for pathological scar.

CONCLUSIONSThere was a certain relationship between p53 gene codon 72 C allele and pathological scar formation after caesarean section.
