Objective To explore the diagnostic value of Reid Scores under colposcopy in cervical human papillomavirus (HPV)infection. Methods Cervical biopsy under colposcopy was carried out for cervical diseases in 528 patients.With pathological findings as criteria,the value of Reid Scores under colposcopy in diagnosis of HPV infection was analysed.Results The coincidence of Reid Scores under colposcopy in diagnosis of HPV infection and cervical intra-epithelial neoplasia(CIN)was 52.66%,with the sensitivity of 51.05%in diagnosis of low-grade cervical diseases(HPV infection and CIN I)and that of 66.67%in diagnosis of high-grade cervical diseases(CIN Ⅱ and CIN Ⅲ).For the patients with diagnosis of HPV infection examined by pathology,the scores of items of boundary,color and vessels were positively related to the total Reid Score,while the scores of items of boundary and color were not related to that of vessels. Conclusion There may exist clinical significance in diagnosis of HPV infection by colposcopy in combination with RCI Scores.

Glucocorticoids have remained important anti-inflammatory agents in the treatment of chronic kidney disease (CKD).However,the use of glucocorticoids can invoke or enhance insulin resistance,which is closely associated with renal injury and serves as an independent risk of the occurrence and progression of CKD.On the other hand,CKD patients may have insulin resistance,which hampers the use of glucocorticoids in these patients.

Objective To investigate the effect of astilbin on expression of CTLA-4 in activated T cells of mouse heart transplantation model with acute rejection.Methods Cardiomyocytes of BALB/ c mouse and spleen cells of C57BL/6 mouse were separated.The cardiomyocytes(2?10~5/ml)as irri- tation cells and spleen cells(1?10~6/ml)as responsers were mixed and cultured.The model of mouse heart transplantation with acute rejection in vitro was established.Three groups were set up:control group,Astilbin(15/?g/ml) group,Astilbin+anti-CTLA-4 mAb 9H10 (30?g/ml)group.Apoptosis of T cells was observed by TUNEL.The expression of CTLA-4 in activated T cells was detected by RT-PCR and Western blot.Results Apoptosis indexes of activated T cells in Astilbin group were sig- nificantly higher than those in the control group(73.4%?12.5% vs 35.1%?9.2%,P＜0.01). The expression of CTLA-4 in Astilbin group was significantly higher than control group(P＜0.01), but there was no apparently difference between control group and Astilbin+CTLA-4 mAb group(P＞0.05).Conclusion Astilbin induces apoptosis of activated T cells in heart transplantation,which may be partially related to its enhanced expression of CTLA-4.

Objective To summarize the experience of laparoscopic appendectomy(LA). Methods A retrospective analysis was made on clinical date of 368 cases of appendicitis treated with laparoscopic appendectomy in this hospital from March 1998 to March 2005.There were 35 cases of simple appendicitis,276 cases of suppurative appendicitis,39 cases of appendiceal perforation with peritonitis,and 18 cases of chronic appendicitis. Results The procedure was successfully accomplished in 363 cases,while conversions to open surgery were performed in 5 cases.The operative time was 22~55 min(mean,30.5 min),and the intraoperative blood loss was 2~10 ml.One case of abdominal residual infection and 1 case of adhesive ileus were cured with conservative treatment postoperatively.Pelvic abscess occurred in 1 case and was cured with a re-operation of laparoscopic abscess drainage. Conclusions Laparoscopic appendectomy is safe and effective in skilled hands.

OBJECTIVETo evaluate the effect of the oral-appliance in the treatment of ED induced by obstructive sleep apnea-hypopnea syndrome (OSAHS).

METHODSThis study included 40 cases of OSAHS-induced ED. Based on the apnea-hyponea index (AHI) and lowest SaO2, we divided the patients into groups A (AHI < or = 30/h and lowest SaO2 > or = 80%) and B (AHI > 30/h and lowest SaO2 < 80%), and treated them with the oral-appliance for 3 months, followed by evaluation of the therapeutic effect using polysomnography, IIEF-5 questionnaire and Sexual Encounter Profile (SEP) diaries.

RESULTSThirty-seven of the patients accomplished the treatment, 16 in group A and 21 in group B. Compared with the baseline, the AHI was significantly decreased in both groups A (21.4 +/- 7.3 vs 14.2 +/- 6.6, P < 0.05) and B (51.4 +/- 9.5 vs 29.7 +/- 8.1, P < 0.05) after treatment, the IIEF-5 scores increased, even more remarkably in B than in A (3.36 +/- 2.48 vs 1.12 +/- 1.27, P < 0.05). The positive rates of SEP2 and SEP3 were markedly lower in A than in B (37.5% vs 76.2% and 25.0% vs 61.9%, P < 0.05).

CONCLUSIONThe oral-appliance can improve the erectile function of OSAHS-induced ED patients, particularly for those with severe OSAHS.

Polysaccharides with multiple biological activities are usually considered as one of the major bioactive compounds in Chinese medicines (CMs). At present, the development of drug and functional foods related to polysaccharides have attracted a great deal of attention due to their great potential effects and diverse action mechanisms. However, quality control of polysaccharides is the bottleneck and a challenge due to their complexity and chemical diversity. Actually, the bioactivities of polysaccharides are closely related to their molecular structures. In order to ensure their safety and efficacy, the development of novel approaches based on the molecular structures for the improvement of quality control of polysaccharides is significantly important. Therefore, in this article, the relationship between biological activities and chemical structures, as well as the action mechanisms of polysaccharides from CMs were summarized first. Furthermore, saccharide mapping, a novel strategy for quality control of bioactive polysaccharides from CMs, was introduced and the application and perspectives were also discussed.

Protein is the executor of physiological function, and direct embodiment of the life phenomena. Proteomics aims to systematically clarify all or parts of proteins' role and function in life movement. In post genome era, proteomics began to play more important role in life science field. Actinobacteria are closely linked to human production and life, which have produced many clinically important secondary metabolites, including antibiotics, antitumorals and enzymes. Actinobacterial systematics and its model organism Streptomyces coelicolor in 2001 genome sequence laid the foundation for further functional genomic studies. Actinobacterial proteomics was more directly and exactly to interpret the activity of life than genomics and transcriptomics, which grew much faster and received so much attention from scientists in the near years. Complex morphological differention, stronge environment adaptiveness, nitrogen-fixing capacity, metabolic mechanism, pathogenicity and natural produces' discovery were systematically reviewed in this study, which was expected to be the basis for promoting Actinobacterial proteomics study in the near future.

Background Plasticity of visual system is one of the mechanisms of deprivation amblyopia.Our previous study showed that synapsin plays a role during visual developmental plasticity,and conventional protein kinase C-γ (cPKC-γ) probably is one of upstream kinases of synapsin.However,whether or how the cPKC-γ plays its effects on visual developmental plasticity is below understood.Objective This study was to investigate the dynamic expression of cPKC-γ in visual cortex of normal mice and explore the effects of abnormal visual experience on cPKC-γ expression.Methods The bilateral visual cortex tissues were obtained from 36 clean C57BL/6 mice at postnatal (P) 7,14,21,28,35,42 days respectively and 6 mice for each for the researching of cPKC-γ dynamical expression in visual cortex over aging.Other 24 C57BL/6 mice were randomized into developmental phase group and adult phase group,12 for each group.The monocular deprived (MD) models were established by suturing the upper and inferior eyelides in P14 mice for 14 days in 6 mice in the developmental phase group and 6 healthy mice served as controls,and MD models were established in the same way in 6 P60 mice in the adult phase group,and the same aged mice (6 mice) were used as controls.The mice were sacrificed and bilateral visual cortexes were obtained.The expression of cPKC-γ protein in the visual cortex was quantitatively detected using Western blot assay.The study protocol was approved by Ethic Committee of Tongren Eye Hospital.The use and care of the experimental mice followed the ARVO Statement.Results The cPKC-γ protein was faintly expressed in visual cortex in normal P7 mice,with the related expressing level of (39.74± 11.22)％ and (40.78± 10.37)％ in the left and right cortex,respectively.The expressing level of cPKC-γ protein was gradually increased over aging,with the peak value of (138.68±15.73)％ and (138.47±23.48)％ in P21 mice.A significant difference was found in the expression of cPKC-γ protein in various ages of mice (Fage =57.174,P =0.000),and the expression of cPKC-γ protein was not significantly different between the left and right visual cortexses (Flateral =0.059,P =0.809).No significant differences were found in the expression of cPKC-γ protein on bilateral visual cortexes among the mice of the developmental phase group and adult phase group (Fage =1.798,P =0.159) or among the MD group and normal control group (Fgroup =0.104,P=0.749).Conclusions The dynamic expression of cPKC-γ in the visual cortex of normal mice presents a consistant tend with the aging and development of visual critical period.MD does not affect the expression of cPKC-γ protein in bilateral visual cortexes.Further researches should be performed in the activity of cPKC-γ protein in MD mice.

Background The treatment timing and method of amblyopia rely on the plasticity of visual system.Synapsin is a family of presynaptic terminal specific protein.Its role in visual developmental plasticity is below understood.Objective To investigate the dynamic expressions of synapsin (T-synapsin),and phosphorylation of synapsin (p-synapsin Ⅰ a/b) in visual cortex of normal mice and further explore the role of synapsin in plasticity of visual system.Methods Forty-two clean neonatal C57BL/6 mice were collected.The mice were sacrificed at postnatal 7,14,21,28,35,42,60 days respectively to obtain the tissue samples of visual cortex.Expression levels of T-synapsin and p-synapsin in the visual cortex following the ageing were quantitatively detected using Western blot assay.Results The expression of synapsin in normal mice showed a dynamic increase with the ageing.The T-synapsin Ⅰ a/b/β-actin value in visual cortex was (21.32 ± 3.27) ％,(56.27 ± 10.18) ％,(77.05 ± 10.05) ％,(83.75±10.52) ％,(94.69±11.46)％,(98.75±5.86) ％ of adults mice (postnatal 60 days,P60) in the mice of postnatal 7,14,21,28,35,42 days,respectively,showing a significant difference among them (F =69.538,P ＜ 0.001).Compared with the adult mice,the T-synapsin Ⅰ a/b/β-actin value in the mice of P7,P14,P21,P28 was significantly lower (all at P＜0.05),but no significant difference was found between P35 and P60,P42 and P60 (P =0.280,0.798).The development trend of different synapsin subtypes,such as T-synapsin Ⅰ a/b,T-synapsin Ⅱ a,T-synapsin Ⅱ b and T-synapsin Ⅲ a,was not quite the same during the ageing.The expression of T-synapsin Ⅱ a and Ⅲ a increasing more slowly with development,and kept increasing until P60.Significant differences were found among various age of mice in T-synapsin Ⅱ a,Ⅱ b,Ⅲa respectively(F =42.492 55.595,39.172,all at P＜0.001).The p-synapsin Ⅰ a/b level in the visual cortex elevated with the ageing of the mice,and that peaked in P21 mice,which was (2.86±0.17) times more than that in adult mice.After that,the expression level of p-synapsin Ⅰ a/b dropped rapidly.A significant difference was found in the p-synapsin Ⅰ a/b expression among different ages of mice (F =22.620,P ＜ 0.001).Conclusions Synapsin level in visual cortex presents a developmental change which correlated with the onset and decline of the critical period.Synapsin is probably involved in the regulation of neural plasticity in visual cortex in critical period.
