Objective To investigate the features of female sexual dysfunction (FSD) in type 2 diabetic patients (T2DM)and to analyze its risk factors. Methods According to FSFI indexes in the sexual function questionnaire,227 female T2DM patients were divided into DM group without FSD [n=144,FSFI≥25] and DM+FSD group[n=83,FSFI<25]. 80 healthy women served as normal controls. The risk factors for FSD were analyzed using logistic regression analysis. Results The occurrence of FSD was 36.6%(83/227) in female T2DM patients. The levels of FSH,TSTO and LH were higher,and E2 was lower in DM+FSD group and DM group than those in NC group(P<0.01),but there was no statistical significance between DM+FSD group and DM group(P>0.05). The score of sexual desire[(2.54±0.58) vs (3.76±0.90) vs (4.59±1.22) score],sexual arousal[(2.30±0.42) vs (3.57±0.85) vs (4.81±1.00) score],vaginal lubricate[(3.35±0.29) vs (4.46±1.32) vs (5.14±0.83) score],orgasm[(2.75±0.68) vs (3.40±1.86) vs (4.02±1.25)score] and total score [(17.94±4.15) vs (24.71±6.33) vs (28.13±5.78) score] were lower in DM+FSD group and DM group than those in NC group. The score of sexual satisfaction[(3.45±1.68) vs (4.94±0.93),(4.99±0.86)score] and pain[(3.55±0.50) vs (4.58±0.47),(4.58±0.62)score] were lower in DM+FSD group than those in DM group and NC group(P<0.05),but there was no statistical significance between DM group and NC group(P>0.05). Logistic regression analysis showed that age,BMI and HbA1c were risk factors for FSD in T2DM patients (P=0.029,0.001,0.022,respectively). Conclusion The occurrence of FSD is common in female type 2 diabetic patients. BMI and HbA1c are the main risk factors for FSD.

Objective To explore the effect of swimming training on the microcirculations of cochlea in guinea pigs with tertram ethylpyrazine(TMP) treatment after chronic hypoxia.Methods 28 guinea pigs were divided into normal control group outside of cabin (A) and chronic hypoxia model group (B). After four weeks the model group were divided into the model control group (B 1),TMP treatment group (B 2),swimming training group(B 3) and swimming training with TMP treatment group (B 4).Until the given time,LDF was used to investigate the blood flow of every guinea pig's cochlea.The spiral ligament spreaded-slice optical lens was used to observe guinea pig's vascular veins, capillary appearance and RBC counts.Results There was significant difference in cochlear blood flow(CBF) and RBC counts between B 2,B 4 groups and B 1 group.CBF and RBC counts of B 3 group was improved comparing with B 1 gorup,so did that of B 4 group comparing with B 2.But no significant difference was found.Conclusion Swimming training can relieve the swelling on the thin blood vessel and improve the effect of TMP on the microcirculation in cochlea of guinea pigs under chronic hypoxia environment.

BACKGROUND: Thermotherapy has achieved remarkable therapeutic effect on patients with esophageal cancer. However, there are still some problems which cannot be answered today, such as the damage of esophageal mucosa during deep thermotherapy when metal stent is placed in esophagus. OBJECTIVE: To study the metal stent-caused damages to esophageal mucosa of pigs in radiofrequency hyperthermia. DESIGN, TIME AND SETTING: Observational study which was performed in the Department of Tumor, Affiliated Hospital of Luzhou Medical College from October 2004 to January 2005. MATERIALS: 13 pigs weighing 35-40 kg were used in this study. Esophagus stent of memory alloy with membrane was provided by Zhiye Medical Apparatus Institute of Changzhou, China METHODS: Five points were located for measurement, i.e. the middle of the stent, the exit of the stent, 2 cm and 4 cm a distance from the exit and 4 cm from the entrance. Esophagus of 13 pigs was heated for 30 minutes by SR-1000 radiofrequency hyperthermia machine in frequency of 40.82 MHz, pole plate of 25 cm Ⅱ 25 cm and power of 500-700 W. MAIN OUTCOME MEASURES: The esophageal mucosa was observed with naked eyes. And optical microscopy was used to observe the changes of the esophageal mucosa. RESULTS: Because one pig died of anesthesia and there were troubles of thermal detector lines in 4 pigs, only 8 pigs were included in the final analysis. Level of damage of esophageal mucosa on five temperature checkpoints was observed from grade 0 to 1 in naked eyes, and the difference of damaged level between five checkpoints was not obvious in statistics (H=2.0, P=0.157). Level of the damage was observed from grade 0 to 2 in microscope, and the difference was not obvious in statistics too (H=2.734, P=0.255). CONCLUSION: Influence of the metal stent on esophageal mucosa can be neglected in radiofrequency hyperthermia, and metal stent does not cause obvious mechanical damage or thermal damage to esophageal mucosa of pigs. It is safe and feasible to carry out radiofrequency hyperthermia on placed metal stent esophagus.

BACKGROUND: Growth-associated protein-43, a kind of protein relatedto axonal growth, plays a key role in promoting neural development, axonalregeneration, synaptic growth and structural and functional reconstructionand so on. In the study, we find that cyclovirobuxine D can protect braininjury in rats with experimental cerebral ischemia reperfusion.OBJECTIVE: To observe the effect of cyclovirobuxine D on the expression of growth-associated protein-43 mRNA in hypertensive rats with cerebral ischemia reperfusion.DESIGN: A randomized controlled animal experiment.SETTING: Foshan Hospital of Traditional Chinese Medicine of Guangdong Province; Central Laboratory of Guangdong Hospital of Traditional Chinese Medicine.MATERIALS: Cyclovirobuxine D is alkaloid monomer extracted from Chinese herb buxine. Cyclovirobuxine D powder with national protected traditional medicine number of ZYB20796057 was provided by Nanjing Xiaoyingyao Pharmaceutical Factory. Totally 120 two-to-three-month-old healthy male SD rats, of either gender, with body mass of 90 to 120 g, were used in this experiment.METHODS: This experiment was carried out in Foshan Hospital of Tra ditional Chinese Medicine of Guangdong Province and at the Central Laboratory of Guangdong Hospital of Traditional Chinese Medicine between June 2005 and March 2006. ①Stroke-prone-renovascular-hypertensive-rats models (RHRSP)were created by bilaterally narrowing the renal artery with silk loop clips. Totally 120 rats were randomly divided into blank group (n=20,renovascular hypertensive rats were given no treatments), sham operation group (n=20, rats were given only surgical trauma), model group (n=40, rats were given treatment of cerebral ischemia reperfusion) and cyclovirobuxine D-treated group (n=40, rats were given cyclovirobuxine D).② Unilateral occlusion of the middle cerebral artery ischemia reperfusion models were made with suture-occluded method. 6.48 mg/kg cyclovirobuxine D diluted by 1.5 mL normal saline was intraperitoneally injected into the rats of cyclovirobuxine D-treated group, twice per day; Normal saline was isochronously intraperitoneally injected into the rats of each subgroup of control group, 2 mL once, the method was the same as that of the cyclovirobuxine D-treated group; interval of injection time was 7 hours in each group. Rats in each group were executed on days 1, 7, 14 and 30after ischemia reperfusion. ③ Brain slice was prepared. The expression of growth-associated protein-43 mRNA of rats in each group was detected with in situ hybridization.MAIN OUTCOME MEASURES: ① The expression of growth-associated protein-43 mRNA around ischemia are following ischemia reperfusion for 2 hours. ②The expression of growth-associated protein-43 mRNA in hippocampus following ischemia reperfusion for 2 hours RESULTS: All the 120 rats entered the stage of result analysis. ① Immune in situ hybridization of growth-associated protein-43 mRNA: In situhybridization showed that expression of growth-associated protein-43 mRNA and expression of growth-associated protein-43 mRNA could be detected respectively in the hippocampus and marginal area of hematoma after ischemia and reperfusion.②The expression of growth-associated protein-43RNA around haematoma following cerebral ischemia reperfusion group as not found in blank group and sham-operation group; The expression of growth-associated protein-43 mRNA was found in the marginal zones around haematoma of rats in the model group on the 1st day following ischemia reperfusion and it was significantly increased on the 7th day, gradually reduced on the 14th day and still expressed on the 30th day but less,with significant difference at each time point (P ＜ 0.01); Expression of growth-associated protein-43 mRNA around haematoma at each time point was more in the cyclovirobuxine D-treated group than in the model group ,with significant difference (P ＜ 0.05). ③There was no significant difference of the expression of growth-associated protein-43 mRNA in hippocampus of rats following cerebral ischemia reperfusion between blank group and sham-operation group; Expression of growth-associated protein-43 mRNA was found in hippocampus of rats in the model group on the 1st day after modeling, and it reached the peak on the 7th day, gradually decreased on the 14th day and significantly decreased on the 30th day, but significantly more than that of sham-operation group; The expression of growth-associated protein-43 mRNA in hippocampus was significantly more at each time point in cyclovirobuxine D-treated group than in model group, with significant difference (P ＜ 0.01).CONCLUSION: Cyclovirobuxine D up-regulates the expression of growthassociated protein-43 mRNA after reperfusion and promotes axonal regeneration of rats with experimental cerebral ischemia.

Objective To determine the characteristics of retinal vascularization in premature infants. Methods A prospective study was carried out which included all premature infants with birth weight<2 000 g, who were hospitalized in Guangdong Women and Children's Hospital from September 1, 2009 to August 31, 2010. Close retinal screening and follow-up were carried out in order to record retinal vascularization at different post-conceptional ages. Spearman correlation analysis was performed for statistical analysis. Results A total of 231 infants were enrolled, and follow-up was completed in 212 infants giving a follow-up rate of 91.8%. Twenty-eight infants developed retinopathy of prematurity (ROP) resulting in a ROP morbidity of 13.2%, and 184 cases had full retinal vascularization. The median birth weight was 1 600 g (1 000-1 900 g) and the median gestational age was 32.4 weeks (27.0-35.5 weeks). In the 32-week post-conceptional age group, the proportion with full vascularization in ZoneⅠ,ⅡandⅢwas 87.1%(81/93), 7.5%(7/93) and 0.0%(0/93), respectively. In the 36-week post-conceptional age group, full vascularization was observed in ZoneⅠ, and the proportion with full vascularization in ZoneⅡandⅢrose sharply at 38-week and 40-week post-conceptional age, respectively. The proportion with full vascularization in ZoneⅢwas 100.0%(24/24) at 43-week post-conceptional age. According to Spearman correlation analysis, there was a positive correlation between ZoneⅡand Zone Ⅲ retinal vascularization progression and post-conceptional age (r=0.690 and 0.720;P=0.000). In premature infants, full retinal vascularization in ZoneⅠoccurred at 36-week post-conceptional age. The median gestational age for ZoneⅡand ZoneⅢretinal vascularization was 38 weeks (32.2-40.4 weeks) and 41 weeks (36.0-42.6 weeks), respectively. Therefore, a further 2-3 weeks were required for full retinal vascularization in ZoneⅡand ZoneⅢ. The time differences for under-vascularization in ZoneⅡandⅢwere 8 to 10 weeks, and the time differences for full vascularization in ZoneⅡandⅢwere 8 weeks and 6 weeks, respectively. Conclusion Retinal vascularization varies in premature infants. Almost all premature infants complete vascularization by term gestational age and the majority of infants need to be followed up to 41 weeks. It is essential to focus on the different retinal regions during maturation.

Objective To discuss the effects of repairing nasal ala defects by free transplantation of autogenous auricle composite tissue flap. Methods 50 cases with nasal ala defects were repaired by free auricular composite tissue flap transplantation from Janu 2003 to May 2013. The defects size was 0.5cm x 0.7cm~1.3cm x 1.5cm. According to the size of the defects, full thick wedge-shaped auricle composite tissue flap were cut off, then inserted into the nasal ala defects area and fixed stablely, the donor sites were sutured directly avoiding ear cartilage. Salvianolate and hyperbaric oxygen were used in postoperative treatment for 5-7 days. Results 48 cases achieved good results, 2 cases had partial necrosis of composite tissue flap after operation, also achieved good results after reoperation. Over 3 months~5 years follow-up, all cases had satisfactory results. The volume of auricle composite tissue flap reduced less than 10%. Surgical incisions had a linear scar, good color matching, nostril symmetry. All patients were satisfied with the overall appearance. Conclusions Autogenous auricle composite tissue flap free transplantation for repairing middle and small size of nasal ala defects can recover ala formation and structure very well, nasal appearance can be improved greatly with nostril symmetry. There is no hypertrophic scar in donor sites. This method is simple and easy,and is also a good method for repairing nasal ala defects.
